What criteria are best suited to check the failure of ductile materials in SOLIDWORKS Simulation?

The best criteria for evaluating the failure of ductile materials in SOLIDWORKS Simulation are based on the principles of yielding and ductility. The Maximum von Mises Stress criterion is specifically formulated for ductile materials and is derived from the distortion energy theory. It accurately predicts yielding by considering the components of stress that cause distortion in the material, making it particularly applicable for ductile materials that undergo plastic deformation.

In addition, the Maximum Shear Stress criterion complements the von Mises approach by assessing the shear stress states that can lead to failure. Ductile materials typically fail due to yielding rather than fracture, and these criteria collectively provide a comprehensive understanding of the material behavior under complex loading conditions.

This combination is effective because it captures the significance of both the average stress state (via von Mises) and the effects of shear, which are critical for ductile failure. Therefore, these criteria are well-suited for analyzing ductile materials in simulations, ensuring accurate predictions of when and how failure may occur.
