ABAQUS VUHARD subroutine problem

Plasticity
User subroutines in ABAQUS
VUHARD

Hello



I am working on the simulation of ring rolling. I have written the subroutine for the plasticity part in the subroutine VUHARD and have set the PLASTIC part in material definition to USER.

I dont have HARDENING PROPERTIES so i have set it BLANK. i have set the path of the subroutine in the job defintion part too. But abaqus crashes whenever i try to do DATA CHECK

It says ABAQUS KERNEL EXITED WITH AN ERROR.I dont know why this problem arises?. I am stuck.

Tensile stress of the concrete

Submitted by mahmood seraji on

Tensile stress; concrete

 Dear friends

 The obtained results from my model show that the ultimate load is higher
than the expected one. after checking the results, I found out that the
tensile stress of concrete is much higher than input value for the
tensile yield stress. "concrete damaged plasticity model"  is applied.

your help is highly appreciated.

What is the best method now to solve advection equation?

Submitted by xiashengxu on
research

I am solving the advection equation which is hyperbolic. Some basic techniques (shown on the page  http://www.cse.illinois.edu/iem/pde/discadvc/) are either of large oscillation or numerical diffusion.

I am striving to find a method without or with little of these problems. Or is there any post correction method to use?

 

Thank you all!
