This research examines the properties of metal matrix composites (MMCs) made from aluminium 6061 T6 with boron carbide and silicon carbide. Aluminium material is a matrix metal with appealing features such as lightweight in nature, high strength and machining with ease. Stir casting is less expensive, simple and used for mass production of MMCs. By adding B4C as (2%, 4%, 6% and 8%) and SiC as constant (5%) reinforcement, the samples are fabricated. The hardness in the material tends to extend by adding the proportion of reinforcement in the metal matrix. Increasing the content of B4C and SiC particles, the MMCs have superior wear resistance.

Grid fins are a type of aero control surfaces used in missiles and rockets in place of more conventional control surfaces such as the planar fins. Conventional planar fins are designed like miniature wings whereas grid fins have smaller lattice aerostructures arranged within a box-like structure. Most grid fins have square grid aerostructures such as those used in the Falcon 9 rocket manufactured by SpaceX. This paper discusses the introduction of 3 innovative designs namely trapezoidal, triangular and hexagonal grids in two configurations - un-tapered and tapered. The taper angles will be 6, 6.5, 7 and 7.5. These new designs will be modelled and analysed using suitable software. The designed grid fins will be simulated in multiple aerodynamic conditions at various angles of attack. The exit velocity of air at the outlet of the grid fin will be measured and analysed in this paper. Once the simulation is complete, the two best designs will be 3D printed with appropriate materials at appropriate scales for wind tunnel testing. The results will be compared and validated with existing data in order to find the overall effectiveness of the designs.

This paper forecasts the transient thermal temperature history during girth welding with a single pass over the welded area on pipe ASME class 300 flange joints of low carbon steel using the moving heat source extension model. Using ANSYS ACT extension for the model of the moving, heat source is simulated for the forecast of the distribution of temperature over the welded region during the welding process like gas metal arc welding. Then due to the residual stress induced by the thermal load of the welding, heat source on the joints is analysed and then comparison of the various heat distribution by changing welding parameters is analysed for optimal welding parameters to reduce the stress. The analysis was carried out on transient thermal and transient structural processes to predict the temperature distribution and residual stress respectively.

The bio-composite materials are compatible with many diversified applications except in marine or submerged instances. An attempt is made in this work to foresee the bio-composite built with Poly Lactic Acid (PLA) as a principal constituent and natural biodegradable fibres (peels of lemon, sweet lime, potato and onion). The project is aimed to build the laminate structure model with the substrate as PLA reinforced with natural fibres using ANSYS Workbench. The simulation test was carried out with various parameters: single impact, uniform pressure, sphere of influence energy absorption. Natural fibre composites were built with a volume fraction of 10%, 20% and 30% of PLA to arrive at optimum results. The computation analysis was carried out using explicit dynamic analysis as a solver and a model of impact analyser was built-in design modeller that is available in ANSYS Workbench. The simulation results are considered for further experimental testing as future work with analytical calculations referred to in ASTM D7136.

The loftiest energy-putting away advancements looked by experimenters are metal-air batteries. Among them, aluminium is a plentiful and enticing anode material for energy capacity and change, as a result of its high unambiguous limit. The hypothetical explicit energy of a promoted lithium-particle battery is 120-200 Wh/kg. The aluminium-air battery has the second biggest limit, coming behind the Lithium-air battery, which is the most grounded auxiliary battery. Three unique kinds of aluminium accessories will be utilized for anode AA5083, certified with multiwall carbon nano tubes, to decrease cell impedance and disintegration. The electrolyte will be KOH. The cathode will be a carbon or graphite plate. An aluminium-air battery has been accessible on demand as an essential battery. To be created as an optional battery, every cell of the battery is compared to anode and cathodes.

The objective of this paper is to provide a solution to a serious issue in today’s world of transportation through railways. The practice to examine the flaws which leads to serious effects in rail track is rail inspection. Among the world countries, Indian railways are the fourth-longest, but when it comes to reliability and safety it lags to provide world standard. As a result, if the track is damaged, it leads to severe loss of valuable human lives and property. This derailment in tracks is caused due to cracks in the rails. Therefore, an early crack detection and protection system is required to save the lives. This paper proposes a customized design of an inductive transducer and crack detection system on railroad tracks to avoid the train accidents. Existing method uses the manpower to identify the cracks and this involves human errors. So, the drawbacks in the existing method can be reduced by the automatic system. Customized inductive sensor is designed and developed using ANSYS. A scaled down model of a cart is fabricated and the inductive sensor is assembled at beneath surface of the cart. The track is acting as a part of the magnetic core for the inductive sensor and voltage is induced in the sensor. The sensor voltage is calibrated to distinguish the magnitude of voltage from the normal to crack.

High lift devices facilitate the achievement of higher Cl on take-off and landing. But the motion of the high lift devices causes unsteady effects that have a significant influence on the resulting lift and drag forces. Hence a 2D unsteady numerical simulation during the retraction of a slat of HL-CRM is conducted to understand the unsteady effects produced during slat motion. Overset grid technique was employed to facilitate flexible motion of the slat. The simulation was carried out using OpenFOAM. It is observed that the value of lift coefficient decreases and drag coefficient increases in steady-state cases, because of the wake region created behind the slat at deployed position and airfoil. As in the transient case, there are huge fluctuations at the beginning of the motion and the fluctuations stabilize at the end emphasizing that the position of the slat during motion affects the entire flow field.

Blending or supplementing metals with cutting-edge Metal Matrix Composites (MMCs) endeavours to improve the safety, reliability weight and productivity. A hybrid MMC was produced for the chamber liner of cutting-edge diesel motors. Dry sliding wear testing equipment, employing a pin-on-disc wear tester, is used to examine the wear properties of casted hybrid metal matrix composites. The examination shows that the wear opposition of Al-6061 is expanded while adding the chicken bone ash and graphite as support content. Within the current work, effort has been made to survey the tribological properties of aluminium as-projected combination test for Al amalgam and unadulterated aluminium. The operational boundaries were a typical load and sliding velocity of the pin concerning rotating disk at temperature. The medium utilized was dry and wet greasing. The amount of mileage has been decreased altogether in aluminium alloy similar to unadulterated aluminium. Dry condition testing showed huge loads of noise and a similarly more measure of mileage for both aluminium and aluminium alloy. The coefficient of contact for aluminium alloy in wet conditions was roughly steady up to the applied load and then diminished with additional utilization of load while the coefficient of friction for unadulterated aluminium was rising persistently with the load. Evaluation of the corrosion conduct of the aluminium MMC is achieved by the usage of the salt spray method or immersion test and the results are considered.

The purpose of the study is to make quantitative and qualitative analyses on the Metal Matrix Composite (MMC). The MMC comprises aluminum alloy AA6061 as the matrix element and 5%, 10% and 15% by weight of silicon carbide particulate (SiCp) as the reinforcement material, before and after heat treatment. This investigation compares the mechanical properties and metallurgical characteristics of the MMC with the base material AA6061. In the present investigation, stir casting method is used for preparing samples of MMC. The produced composites were subjected to heat treatment to enhance their hardness. The influence of the weight composition of the reinforcement particles on the mechanical properties of the MMC is analyzed quantitatively. The mechanical properties such as tensile strength, impact strength and hardness were measured for quantitative analysis, while scanning electron microscope is used for qualitative analysis. The temperature of the furnace and the hardening time during the heat treatment process control the hardness exhibited by the composite materials. The percentage composition of reinforcements in the composite materials influences their mechanical properties. Based on the results, optimal material has been suggested for a wide range of applications. The proposed investigation indicates that if the heat treatment increases, then the microhardness of the MMC increases by 13.86%, 18.45% and 30.19%, respectively for 5, 10, and 15% by weight SiCp. It is also observed that the maximum tensile strength of MMC is 329 MPa at 10 % by weight of SiCp. Compared to the base material, it is a 12.5% increase in its tensile strength. Increase in the percentage composition of SiCp to 15wt. % reduced the impact strength by 13%. The scanning microscopy reveals that MMC having 10% by weight of SiCp has a medium-size grain structure.
