Review of a few "Unified" Viscoplasticity Models (Motivated by solder deformation)
I had prepared this document for a class project, the level is introductory and the selection of models is motivated by solder deformation, but I hope it is of some help. I have examined four models, proposed by Hart, Anand, Krempl and Busso. The document has 16 pages.
Thanks,
Dhruv

Anand's model in ABAQUS
Hi Dhruv,
I am trying to model a double lap shear in ABAQUS. In Abaqus version 6.7 and above, Anand's model can be invoked by editing keywords and adding necessary data lines in keyword editor. I am facing some prblems in running the job analysis and since I am new to working with ABAQUS, I am not able to solve the problem. The problem is, when I submit the job the status keeps on showing "Running" without showing any error or warnings. I have tried all both coarse and finner meshes so i think there is no problem with convergence.
Thanks,
Luv Sharma
