  Hello,
  
  Is there a way to have Ansys calculate the load required to yield a material in a component?
  
  Thanks,

  Hello Sam,
  
  Use a linear elastic material: just Young's Modulus and Poisson's Ratio.
  
  Apply a unit load, F = 1 lbf and solve.
  
  Insert the Equivalent vonMises Stress result and obtain the maximum Stress, Sm.
  
  The load Fy required to reach the Yield Stress, Sy is
  
  Fy = Sy/Sm.
  
  Since everything is linear, the ratio of forces is equal to the ratio of stress.
  
  That assumes you have done a Mesh Refinement Study and have converged on the exact maximum stress.

  Hi If you consider nonlinearities in your setup,you have to run for higher load with enough substeps to predict failure.no shortcut.
