Altair Forum User

Hi,

 

I manage to complete the tutorial.

 

But when I modify or change my material model, problems encountered when solved in Radioss.

 

Please refer to picture attached for further details.

 

Thank you in advance.

Hi,

 

I think you are missing the plasticity curve in the Material LAW.

 

The tutorial is based on material law 2 and what you are using is material LAW 43. Please make changes accordingly. Instead of LAW 43 try with LAW 32 which is similar to 43 but differs in inputs (you can avoid curve in LAW 32)

Hi,

 

Thanks for the reply.

 

I wish to do the material calibration like show in HS-4200 Material Calibration Using System Identification.

 

The material law implied in Hyperform is law 43. So, if I use law 32, is it not compatible with my objective?

 

How to import those curve if I insist want to use law 43?

 

Thank you.

LAW 43 and 32 are same the only difference is yield parameter is user defined in LAW 43

 

Please refer help for more information on /MAT/LAW 43 and LAW 32

Hi,

 

I faced new errors again. I use law 32 as my material  but the errors blamed the property now.

 

Please help.

 

Thank you very much.
