A Stress-Strain Curve in SOLIDWORKS Nonlinear Analysis is a graph of user-defined stress and strain data points that make a graph that the Nonlinear Analysis program can use to obtain a lot of useful information. Information like the yield point of the material (which should always be the very first point in any SOLIDWORKS Simulation Stress-Strain Curve), material strength, ductility, formability, elastic modulus, etc. In fact, only the Poisson’s ratio (NUXY) is taken from the Material dialog box once a Stress/Strain Curve has been defined for a material.
An example of a SOLIDWORKS Nonlinear analysis Stress-Strain Curve is shown below.
Different types of stress and strains can be utilized when defining a Stress-Strain Curve these are defined below:
Now that these values have been defined the table below summarizes when each value should be used.
