We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hi Farhana,

For the Bilinear Isotropic Hardening model, the entry “tangent modulus” specifies how your material work hardens.

The tangent modulus in your model is significantly small, meaning that the material’s behavior is similar to a perfect plastic material with almost no increase in the stress with plastic deformation. This explains what you observed in the results. Please ensure that this is the expected behavior for your specific material and if not, adjust this parameter accordingly.
