ES 246 Project: Large Deformation Plasticity of Amorphous Solids, with Application and Implementation into Abaqus
http://imechanica.org/node/add/imageI propose to investigate an elastic-viscoplastic constitutive model proposed by Anand and Gurtin [1] for the large deformation of amorphous solids. Specifically, I will present the constitutive framework proposed for elastic-plastic amorphous materials, I will implement the constitutive equations into Abaqus/Explicit, and I will compare numerical results with experimental results for polycarbonate [2].

Hello;
I am a student in mechanical, I work on polymer materials, I order to implement the model Aruda - Boyce, I have a problem to do so. Is what you can m'aidé?
Thank you
fracture mechanics project
hello
i am lokesh,pursuing M.TECH from IIT MADRAS.i want to do project in fracture mechanics.from last 2 month i am searching for a problem.i have only 5 month to complete project.can you suggest me some project about fracture mechanics.
ialso want to know about 2d and 3d crack propagation simulation.is it good problem?can we use only matlab for crack propagation simulation?i want to know other possibilities for performing crack simulation?please help me and suggest good projects,which can be completed in 5 months.
thanks
regards
lokesh choudhary
