This document is a report on various failure models today useful for identifying failure in thin sheets of high strength steels. Emphasis has been given on phenomenlogical models and only some easy simulations have been performed. The phenomenlogical models which are described listed here are of 4 diverse types, specifically stress based, strain based, combined stress and strain based and damaged models.
Dynamic analysis of damages in materials is a difficult task and it is currently not known what importance different possible mechanisms carry. It is to a large extent due to the difficulty of measuring the dynamic behavior of cracks, debonds and delaminations
Plastic tearing occurs in compact tension (C(T)) specimens fabricated from ductile steels. This tearing, however, is not an elastic fracture problem governed by a crack tip singularity parameter. The current application of the J-integral and the J-R curve to plastic fracture mechanics…
The effect of process-induced voids on the durability of Sn-Pb and Pb-free solder interconnects in electronic products is not clearly understood and researchers have reported conflicting findings. Studies have shown that depending on the size and location, voids are not always detrimental
Composite bridges are used for road and railroad bridges in Sweden and worldwide. The advantage of composite bridges is that concrete and steel is used optimally, steel in tension and concrete in compression. In order to get the interaction between steel and
