1D PROBLEMS

Read Sections 1.1-1.4 in text.

Hwk Set #1.
1. Extend the formulation of the incremental elastoplastic IBVP/return-mapping algorithm for the case of combined isotropic/kinematic hardening using the flow/hardening rules given in the text (see Section 1.4.4, text).

2. Computer: Implement the above incremental formulation in a program that accepts as input the incremental total strain for a given sequence {n=1,2,...,N}. (Hint: you must initialize all other variables to be zero at the first increment. Create a single array to contain all "history" variables. This will be useful for extending the program to other models and for passing data through an argument list.)

2D/3D PROBLEMS

Hwk Set #2.
Computer: Implement and run the ABAQUS User Subroutine (UMAT)-see Fortran Programs); execute the test problem in the associated handout.
