In this example, a snap fit connector is pushed into the corresponding boss, and then pulled back out. Example 2: Snap Fit Connectorĭesign of snap fit connectors or clips are another great potential application for nonlinear analysis. Stresses and deformations in an unloaded state. Predicting that kind of damage with SOLIDWORKS Simulation requires careful engineering determinations based on approaches such as comparing relevant stresses to the ultimate strength of material or observing strains.Īpplied loads can be removed at the end of a nonlinear study to output residual It’s worth noting that finite element models in nonlinear studies will show distorted shapes but never damage like ruptures, cracks or tears. The only conclusion that can be drawn from stresses above yield in a linear static study is often that “yielding is likely to occur”-the values reported over yield must not be relied upon without first investigating a plasticity model in a nonlinear study. Regions have produced a redistribution of the locally high stresses aroundįor these reasons, linear material models are generally an inaccurate predictor of stresses above yield.
