What criteria are most appropriate for checking ductile material failure in SOLIDWORKS Simulation?

In the context of checking ductile material failure in SOLIDWORKS Simulation, the criteria of maximum von Mises stress and maximum shear stress are most appropriate because they relate directly to the behavior of ductile materials under load.

Ductile materials are characterized by their ability to deform plastically before fracturing, and the von Mises stress criterion is widely used to predict yielding in such materials. This criterion is based on the distortion energy theory, which indicates that yielding starts when the equivalent von Mises stress reaches the yield strength of the material. It effectively accounts for the complex state of stress in components, which is critical in ensuring accurate predictions for ductile failure.

In addition to that, the maximum shear stress criterion is also relevant because ductile materials tend to fail not only due to normal stresses but also due to shear stresses that can lead to plastic deformation. Evaluating both von Mises stress and shear stress allows for a comprehensive assessment of the material's failure potential under various loading conditions, ensuring that designs can accommodate the necessary safety factors and operational requirements.

The other options mentioned employ different criteria that may not be as suitable for the ductile materials in question. Thus, option B stands out as the most aligned with the failure characteristics of ductile
