The sensitivity analysis shows that pulse duration parameters, wire speed, and discharge flow are most effective parameters for cutting rate, and pulse duration parameters, dielectric rate, and discharge flow are most effective parameters for surface roughness, as well as pulse duration, wire speed, and discharge current for gap width. Pulse duration with 72%, wire speed with 14%, and discharge current with 10% has the greatest impact on the chip removal rate.

Phononic crystals are inhomogeneous structures which are created by periodic arrangement of inclusions in an elastically different host material. By removing of a row of inclusions, phononic crystal waveguide can be obtained. In this research, effects of structural defects on a phononic crystal heterostructure waveguide have been investigated. The heterostructure is composed of square and triangular phononic crystals (periodic arrangement of steel inclusions in epoxy host). To analyze the structure, displacement based finite difference time domain method has been used. The simulation shows that a stub attached vertically to the heterostructure waveguide induces dips in the transmission spectrum. Also, the frequency range of the transmission was limited to a narrow frequency domain of 104 Khz in the cavity-containing waveguide. Finally, the simulation showed that the effect of the cavity that is inserted at the side of the waveguide is insignificant.

percentage of nosing is expressed based on the effective parameters, and finally, the optimal percentage of nosing for the regression equation obtained by the genetic algorithm is obtained. percentage was determined by the experimental design method. In this research, response level method and central composite design were used. Variance analysis method is used to check the relationship between output variables and input parameters. The results show that as the wall slope increases, the percentage of nosing increases and as the thickness and friction coefficient increase, the percentage of nosing decreases. It can also be seen that, to increase the percentage of nosing, the slope of the wall should be high and the friction coefficient should be low. Also, by using the genetic algorithm and optimizing the regression equation obtained from the analysis of variance, the maximum percentage of nosing has been obtained at 60.81.

Refineries and petrochemical industries, due to the presence of all-metal equipment and acidic environment, have high corrosion. This study investigates the effect of ultrasonic shock on the corrosion behavior of 316 stainless steels in order to the increasing use of stainless steels in these industries. The aim of this study was to investigate the effect of ultrasonic stress relief method on increasing the strength of parts in corrosive environments. It should be noted that the residual stress in the samples is created by welding. In this study, first the considered sample is De-tensioning using ultrasonic vibration at a frequency of 20 kHz, then the obtained results are compared with the results of samples without De-tensioning operation and also thermal De-tensioning operation. XRD method used to measure the residual stress. The obtained results show that in ultrasonic method and heat treatment, the amount of residual stress is reduced by 58.7% and 54.3%, respectively. It has also been observed that the use of ultrasonic waves has increased the life of the sample in a corrosive environment.

machine have been designed and fabricated and then, the low-pressure hydroforming process of aluminum tube is performed and the round section of the tube is transformed into a rectangular cross section by the hydroforming process. Also, the thickness distribution and the values of the radius of the formed corner are investigated under three different loading paths. The results show that by increasing the internal pressure, a smaller corner radius can be achieved but the thinning increases. Also, the maximum flat surface of the upper part is obtained when the upper mold is displaced after the internal pressure reaches its maximum value.
