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.
SOLIDWORKS Simulation first calculates displacements of all the nodes in the mesh. The strains are then calculated, and the last stresses for each element in the mesh are calculated. Stresses are calculated at specific points within each mesh called Gaussian or quadrature points. After the Gaussian point has been calculated for an element, the program calculates the nodal stress for each element by extrapolation.
Meshing plays an important role regarding the accuracy of a SOLIDWORKS Simulation analysis. The linear static study module includes an option that allows for the solver to adapt the mesh during the solution in regions of the model with high strain energy errors. This results in a more accurate solution with little user input. There are two types of solution adaptive mesh refinement methods that can be used: h-adaptive and p-adaptive. This guide will cover the differences between the two methods and how to enable them.
CircuitWorks includes basic support for SOLIDWORKS PDM, enabling it to search the SOLIDWORKS Vault for components to use in the assemblies it builds. This article explains how the integration works and how to configure SOLIDWORKS PDM and CircuitWorks to work correctly.
