advanced high strength steels (ahss) have recently attracted great attention because of their superior mechanical properties. a modern group of these steels, known as twinning induced plasticity (twip) steels, shows a unique combination of strength and ductility even at high rates of strain. in order to examine the functionality of such steels in dynamic loading conditions, their mechanical beh...

Processing map for hot working of Ti-IF steel has been developed in the temperature range of 750 to 1100 °C and strain rate of 0.01 to 100 s-1. This map in the austenite region exhibits a single domain with a peak efficiency of 45% occurring at 1025 °C and strain rate of 0.02 s-1. The domain extends over the temperature range of 1000 to 1100 °C and strain rate range of 0.01 to 1 s-1. The true s...

the problem of several finite moving cracks in a functionally graded material is solved by dislocation technique under the condition of anti-plane deformation. by using the fourier transform the stress fields are obtained for a functionallygraded strip containing a screw dislocation. the stress components reveal the familiar cauchy singularity at thelocation of dislocation. the solution is empl...

construction of asphaltic core dams is a relatively novel method especially in iran. iran is located in a region with high seismicity risk. therefore, many researchers have focused on the behavior of such types of dams under earthquake loading. in this research, the behavior of asphaltic core rockfill dams (acrd) has been studied under earthquake loading using nonlinear dynamic analysis method ...

effect of small al additions, from 0.14% to 0.31% ai, on the hot deformation behavior of low carbon steels containing 1%cu-1.2%mn was investigated in the temperature range of 750-800•c over the strain rate range of 1o.3.1o.1s•1 by a hot compression testing machine. the flow curves obtained, exhibited typical characteristics of dynamic recovery type of softening mechanism, and the critical strai...
