Week - 10 Hyperelastic Material Models

AIM:

With given stress-strain value need to find Engg stress-Engg strain

Given DOGMEN-SPECIMEN to to compare with given stress-strain values.

Create BOUNDARY_PRESCRIBED_MOTION_SET

Create BOUNDARY_SPC-SET for left side of test.

Apply values to the curve

Then DEFINE_CURVE for PRESCRIBED_MOTION SET.

Create MAT_OGDEN_RUBBER

Create section_shell

X-STRESs PLOT

Effective plastic strain plot

Lower Ipt x-strain plot.

MAT_77 card need to create constant N1,N2,N3 values.

RESULT:

The final simulation.

CONCLUSION:

Thus the model the mooney rivalan material card and ogden card and with these card we have performed tensile test and compared the result of experimental data with the simulation data and we csan conclude that the ogden material which has higher order gives accurate result when the compare to the mooney rivalan constants.
