my project is life prediction of elastomer gaskets in ic engines using fea. how can i select the constitutive model and the life prediction associated with which mechanism whther stress relaxation, stress softening or excessive creep
I 've mater thesis project about prestress concreate bridge. On the first step I used Bolt load for represent prestress on Tendon
to hold all bridge block. And second step I apply load on vertical load such as 3 point bending test. On the first step I can run it completed. But on the second step it not converge. I need some comment for help mesolve this problem
I post some (hand-written) notes on compatibility conditions for both small and finite strains that I have used for helping me in lecturing. These may be useful for our student friends on imechanica. I also post a paper on compatibility conditions for the Left Cauchy-Green field in three dimensions as well as the paper by Janet Blume on the same subject.
