In SOLIDWORKS Simulation, the Factor of Safety (FOS) calculations are based on which of the following failure criteria?

The Factor of Safety (FOS) in SOLIDWORKS Simulation is traditionally calculated based on maximum normal stress criteria. This approach evaluates whether the maximum stress experienced by a material under load remains within a safe limit compared to its yield strength or ultimate strength.

Using the maximum normal stress criterion, the FOS is determined by comparing the applied tensile or compressive stress to the material's yield strength. If the maximum normal stress resulting from applied loads is less than the yield strength of the material, the design is considered safe. This method is commonly used in engineering applications where failure is assessed based on whether a material can sustain the maximum expected loads without yielding.

The other criteria, such as maximum von Mises stress or maximum shear stress, although important in different contexts, are generally associated with other forms of stress analysis and aren’t the primary focus for determining FOS in terms of maximum normal stress. Thus, understanding that maximum normal stress forms the foundation of FOS calculations provides clarity in both design and analysis within the realm of SOLIDWORKS Simulation.
