Is there any example about foam compression test simulation?

Hello everyone,

I want to simulate the foam compression test. Is there any example or any suggest on how to do it? Thank you.

Hi Roy,

Unfortunately we don't have any tutorials or examples for foam compression tests.

We can use /MAT/LAW33 (Visco-Elastic Plastic Foam Material) or /MAT/LAW70 (Visco-elastic Foam Tabulated Material) for modelling foam.

Please go through a case study on the same at http://www.altairatc.com/(S(rfs4o2whprtbiaaazxof4unk))/europe/presentations/Session10/Session10_Ford_Schilling.pdf

Hi Naresh,

Unfortunately, the above PDF file is not currently available.

You can find out more info about /MAT/LAW33 and /MAT/LAW70 in the following links:

/MAT/LAW33

• https://help.altair.com/hwsolvers/rad/topics/solvers/rad/mat_law33_foam_plas_starter_r.htm
• https://help.altair.com/hwsolvers/rad/topics/solvers/rad/theory_material_laws_viscous_materials_visco_elasto_plastic_mat_foams_r.htm

/MAT/LAW70

• https://help.altair.com/hwsolvers/rad/topics/solvers/rad/mat_law70_foam_tab_starter_r.htm
• https://help.altair.com/hwsolvers/rad/topics/solvers/rad/foam_material_verification_intro_r.htm#foam_material_verification_intro_r_reference_rsf_rgd_zrb  (Verification Problem)

The second link for /MAT/LAW70 contains also an example in which this material law is used.
