    Fatigue Analysis-Goodman criteria

    Hi all, Lets say, I have 2 load cases, LC1 and LC2. For LC1, the principal stresses are S11,S12,S13. For LC2, the principal stresses are S21,S22,S23. To calculate mean and alternating stresses. If S11>S21, then mean = (S11+S23)/2; Alternating stress = (S11-S23)/2. If S11<S21,then mean =...

    Combining load cases in Ansys WB

    Hi all, I have two load cases, LC1 and LC2 that have different loading conditions. I want to add stress values of LC1 and LC2. For example: Let S11, S12, S13 are principal stresses of node 1 for LC1 and S21,S22,S23 are principal stresses of node 1 for LC2. I want to get the summation values...

    Endurance limits of new material

    Hello Everyone, We make the castings using our own material.we performed RR moore rotating beam test and found the endurance limits through curve fitting of S-N curve. Do we have to use modifying factors to further reduce the endurance values? What is the general procedure to accept a new...

    Incorporating residual strains in Ansys

    Hi, I am trying to model a composite beam using Ansys. I wanted to know how to incorporate Residual Strains using Ansys? I have tried but in vain. If someone knows a method of incorporating residual strains or stresses for a composite beam using Ansys, the response will be of immense help. Thanks!
