Equal channel angular pressing (ECAP) is one of the most prominent severe plastic deformation (SPD) processes to achieve ultra-fine grained (UFG) structures. Using bimetallic specimens has been recently considered in this ...

to optimize the die geometry of TCP through a finite element simulation procedure verified by experiments in order to increase the imposed strain as well as decreasing the strain heterogeneity. Results show that the increase in die curvature radius causes...

the instability number defined in this article, the rotation angle of the micromirror is increased and suddenly the pull-in occurs. The results of the presented model are then verified by comparing them with the results of finite element simulations performed...

-dimensional (3-D) finite-element simulator are applied to achieve the thermomechanical stress distribution under different temperatures for the different structures fabricated by QMIT. A closed-loop temperature measurement system consisting of a Pt-100...

The bodies of aircraft structures have a lot of fastener holes and under different situations

these holes bear external forces, which cause a tensile stress on the surface that leads to the failure of

materials. ...
