Isotropic & Kinematic hardening

This video gives a basic overview of the most fundamental hardening models of plasticity, which are the isotropic and kinematic hardening

 

Hope this helps!

ABAQUS (6.8, 6.9 EF) - Effect of the number of back stresses

Since ABAQUS 6.8, a new feature has been added to the combined hardening
material input.

Let's assume a combined Kinematic and Isotropic hardening case, such as
those happen in metals.

"Half cycle" uni-axial test results has been utilized to model the yield
stress-plastic strain behavior as well as the Kinematic behavior of the
metals.

In the same user interface,  there is an option to choose the number of
back stresses.

Is the number of 1 back stress is equivalen to the case of linear kinematic hardening (Ziegler's)?

Writing User Subroutines with ABAQUS

Dear All,

 I think that many students are looking for some tutorials about writing a UMAT in ABAQUS.

You can find a comprehensive tutorial for elastic problems.
