Investigation of Important Parameters in Residual Stress Determination in Isotropic Plates and Laminated Composites by Slitting Method
In the slitting method, a small width slit is created incrementally through the thickness of the stressed specimen and the released strains in each increment are recorded by a strain gauge. Compliance coefficients relate the measured strains to the residual stresses. This paper investigates the important parameters influencing the calculation of compliance coefficients for isotropic plates and ...
متن کاملMeasuring of Residual Stress in TIG Welding of the 304 Stainless Steel by Ultrasonic Method
In this research, the effect of different welding parameters on residual stress and microstructure of the weld region, as well as the comparison of two methods of measuring residual stress using critical fracture longitudinal wave method and preformation method have been investigated. For this purpose, the taguchi DOE methodology is used as a statistical method to optimize four parameters of pu...

متن کاملNanopowders produced by electrical explosion of wires
Electrical explosion of wires (EEW) is a method for production of nanopowders. Depending on type of chemical composition of working ambient in the discharge chamber nanopowders of carbides can be produced (EEW in hydrocarbons) or nanopowders of oxides (EEW in oxygen contained medium). Phase compositions of nanopowders prepared by electrical explosion of tungsten and aluminium wires in liquid an...
