21 Jun Equivalent Stress
The stress results of a FE analysis are three-dimensional tensors, see: (https://fea-solutions.co.uk/stress-tensor/) Material properties including Yield Strength and Ultimate Strength are however usually derived from uniaxial tests, e.g. tensile tests, see: (https://fea-solutions.co.uk/tensile-tests/) Depending on the material used and its failure mode, there are different conversions done: For...
