Generalized plasticity models

[double]

Dear FEAPers,

I am trying to duplicate the numerical example of the paper:

@article{AURICCHIO199565,
title = "Two material models for cyclic plasticity: Nonlinear kinematic hardening and generalized plasticity",
journal = "International Journal of Plasticity",
volume = "11",
number = "1",
pages = "65 - 98",
year = "1995",
issn = "0749-6419",
doi = "https://doi.org/10.1016/0749-6419(94)00039-5",
url = "http://www.sciencedirect.com/science/article/pii/0749641994000395",
author = "F. Auricchio and R.L. Taylor",}

with Generalized plasticity models in feap84.  However I have some troubles in setting the material parameter, because the result always shows elastic response.

Could anyone help me with the input file? Thanks!

[Prof. R.L. Taylor]

Did you look at the material properties in the output file?

One suggestion is to use TPLOt to $output the appropriate stress in the loading direction?  Look at the values and compare to the yield stress.

It is always a good idea to leave an INTEractive just before the STOP so you can look more at the problem.
