How to create for single material tension & compression Stress-Strain curve?

Hello Madera,

In SimSolid, to create compressive and tensile stress-strain curves for a single material, you need to define a nonlinear material model that captures the material’s behavior under both tension and compression. This involves inputting stress-strain data tables that represent how the material responds to positive (tensile) and negative (compressive) strains. If your material behaves differently in tension and compression, you can either provide separate curves for each or use a combined multilinear curve that covers the entire strain range, including negative values for compression. These curves are entered in the material editor, where you specify pairs of strain and corresponding stress values. Once assigned to your material, SimSolid will use these curves during simulations to accurately model the material’s nonlinear response. It’s a good practice to validate your material model by running simple uniaxial tension and compression tests to ensure the curves behave as expected. If your version of SimSolid doesn’t explicitly support separate tension and compression curves, approximating the behavior with a single piecewise nonlinear curve spanning both positive and negative strains is a practical approach.
