During the shock tube forming, the sheet metal undergoes plastic deformation at a high strain rate till fracture. Thus, the damage evolution during FE simulation of forming can be obtained by incorporating...

This is accomplished in part by reducing the thickness of silicon substrates in order to obtain more wafers per ingot [ 3 – 6 ]. Given the brittle nature of silicon, thinner wafers are more prone to fracture, which is a common...

For a random fiber orientation case, deformation of the unnotched specimen occurs by long-range fiber chains connecting the load inducing boundaries, and failure is by tearing the cross section. The strength of the notched random...
