To overcome the complexity of the lithium-ion battery inside the chemical reaction resulting in a low battery life remaining prediction accuracy, the paper proposes a new electric vehicle lithium ion battery remaining life prediction method based on a correlation vector machine. According to the operating characteristics of lithium-ion batteries in electric vehicles, this method selects health factors that affect battery life, and selects related factors. According to the marginal likelihood function, the factor weights are integrated to obtain the health factor sequence target. Relevance vector machine is used to optimise and evaluate the characteristics of health factors, and complete the prediction of electric vehicle lithium-ion battery capacity and remaining battery life. Comparative experiments show that the prediction effect and stability of the method in this paper are better, and the minimum prediction error is only 0.013.

Tubular copper to steel joints were manufactured by electromagnetic pulse welding, during which the impact velocity was measured with photon Doppler velocimetry. The reduction in inner diameter and the remaining cross-sectional area of the target tube were determined after welding. Tube-to-tube configurations with an internal support exhibited a larger remaining cross-sectional area, compared to the configuration without internal support. Moreover, for the tube-to-rod configuration, the initial velocity drop immediately after impact dropped down to zero, whereas for the tube-to-tube configurations, a velocity drop to an intermediate level was found. The velocity and acceleration increased with an increase of the discharge energy. The acceleration was positive up to at least 9 μs, with an expected turning point situated between 9 μs and 11 μs. The acceleration was still positive at the moment of impact at a stand off distance of 1.0 mm and 1.5 mm, but was likely negative at 2.0 mm.

The purpose of the paper is to further improve the mixing uniformity of concrete aggregates, thereby improving the quality and mixing efficiency of concrete. Taking the structure of a planetary concrete mixer produced by a company as a reference, the discrete element software EDEM was adopted to simulate the material mixing process and to analyse the mixing uniformity. It is found in the simulation that the aggregates at the side wall of the mixing tank are not mixed evenly when the shape of the side scraper of the mixer is modified from a flat surface to a curved surface. The results show that the structural optimisation makes the trajectory of the aggregates more complicated and improves the mixing quality, the mixing uniformity of the three aggregates being increased by 16%, 10.1%, and 22.1%, respectively. The simulation results of the discrete element can provide reference for actual product design.

Powder mixed electro discharge machining (PMEDM) is the expansion of conventional electro discharge machining (EDM) where powder particles are mixed in the dielectric fluid for acquiring better surface finish and enhancing machining efficiency. Cryotreatment of the electrode is introduced in this study which reduced the tool wear, thus machining cost. In this investigation, SiC powder particles were suspended in kerosene dielectric and the effect of control parameters, cryotreated double tempered (CT2) electrode have been studied on surface crack density (SCD), surface roughness (Ra), material removal rate (MRR) and tool wear rate (TWR). Powder concentration, duty cycle, pulse on time, peak current, and gap voltage were used as control parameters. EDM operation on AISI 304 stainless steel is performed using untreated (UT) and CT2 tungsten carbide (WC) electrodes. It was found that higher material removal rate and superior surface finish obtained in PMEDM over conventional EDM. CT2 electrode gives less TWR and lesser amount of surface cracks than that of UT electrode.

Chemical mechanical polishing/planarisation (CMP) stays a widely used process for complete planarisation in semiconductor fabrication. CMP process provides surface uniformity, high selectivity, low defects with the desired material removal rate. The removal rate is influenced by various independent parameters namely turntable speed, down pressure, slurry pH, and H2O2 concentration. Modelling the CMP process from fundamental principles is limited. Hence, in this study, the design of the experimental methodology has been adopted to design the CMP process. Different models such as linear, quadratic, two-factor interaction, and cubic mathematical were developed and statistically analysed in identifying the suitable model by Box-Behnken design. The consequence of each parameter and their interactions on Ge removal rate is analysed. A quadratic model is proposed from the outcome. The predicted values achieved using model equations exhibited appropriate fit by experimental values (R2 value for rutile and anatase as 0.943 and 0.942, respectively). The present work verified that response surface methodology and Box-Behnken design can be expeditiously functional for modelling of chemical mechanical planarisation.

An experimental study was carried out to evaluate the flexural behaviour of CFRP composite laminate with introduction of open hole as well as by varying stacking sequence. Open hole is required in laminated composites to assemble the components through mechanical fasteners. Degradation in strength was observed due to the presence of a hole. Six stacking sequences have been analysed: [0]8, [90]8, [0/90]2s, [90/0]2s, [02/902]s, [902/02]s in which [0]8 is noticed to have highest flexural and open hole flexural strength. Strength retention is also evaluated in this study to compare retention strength of open hole laminate with laminates having no hole. Existence of both tensile and compressive failure modes during flexural loading makes overall damage mode complex. Furthermore, introduction of open hole in the laminate during flexural loading makes it more complex as variation in stress distribution activates different features of deformation and failures. Fractographic analysis has been done using scanning electron microscope to perceive damage progression mechanism during flexural loading. SEM micrographs confirmed the delamination between 90° and 0° plies as it is seen in stress strain graph as a stress drop.

In the present study, fly ash-based pervious concrete (FPC) is fabricated using sintered fly ash aggregates. Materials used include OPC Type I cement, the coarse aggregate of size 4.75, 9.5, 12.5 mm, water, and superplasticiser. Using these materials, various concrete mixtures were developed with a water to cement ratio of 0.30, 0.35, and 0.40, respectively. The effect of these parameters on the mechanical properties of the pervious concrete such as compressive strength, flexural strength, tensile strength, permeability, porosity, abrasion resistance, and leachability is studied. The test results showed that pervious concrete materials made with sintered fly ash aggregates had a better mechanical as compared to natural available aggregate. In addition, the concrete with SFA aggregates could achieve compressive strength ranges from 7.15 to 17.40 MPa with porosity range from 26.79 to 34.05% and these can be adopted as an environment-friendly concrete.

Shafts are rotating elements that are subjected to torsion and bending moments that cause failures at times leading to personal injury, capacity loss, or poor product quality if basic preventive design actions are not taken. Against this background, this paper describes the failure analysis and root cause of a broken SA564 grade stainless steel pump shaft used in a plant through visual inspection, metallography, X-ray diffraction, scanning electron microscope, chemical analysis, hardness, tensile and non-destructive tests. The results show that creep, fatigue initiation and propagation from defects in the material during the operation were the predominant factors of pump shaft failure. Moreover, the existence of voids, micro-cracks, sensitisation and creeps were also identified on the broken shaft. Overall, the studied broken shaft of the impeller failed due to fatigue, initiated at the fillet radius of the keyway due to the high cyclic stress loading.

Presently, energy harvesting from natural sources is one of the hot-spot areas for actuating the micropower devices used in electronics and instrumentation. The performance and potential of energy harvesting systems depend on the geometry of the structure and properties of the materials employed. The present work focuses on the effect of piezoelectric materials on the structural and electrical characteristics. A three-dimensional finite element analysis is implemented to investigate the power output from a vibrating cantilever beam with three different types of piezoelectric materials namely lead zirconate titanate (PZT-5H), polyvinylidene fluoride (PVDF) and zinc oxide (ZnO). It was observed that the power output strongly depends on the material properties and geometric parameters of piezoelectric patches mounted on the cantilever substrate. To this end, the area and thickness ratio of the laminated beams are varied to understand its effect on the natural frequencies and the electric power output. The output energy increases with an increase in the area of the piezoelectric patch. A similar trend is observed in the case of the thickness ratio. PZT-5H has shown more energy harvesting potential for the same geometrical configurations.
