    Stress Singularity

    Thanks for the reply. Zuardy. Yes, I model the stiffeners with shell element also. I constrained all the six DOF of shell elements at the fastening area. Is that enough or as you said, I have to constrained the rotational shells DOF to their normal. But I don't found high stress at this area...

    Stress Singularity

    Hi, all. I'm working on a linear elastic analysis. The object I analyze is basically a steel plate with some stiffeners. I model it with shell type elements. I find out that the stress at sharp corners of critical joint reports incredibly high. And the stress value tends to increase endlessly...

    Stress and Strain Conversion

    Hi, all. The stress and strain reported from my code will be in Cauchy stress and Logarithmic strain as I invoke the Updated Lagrange option in my code. I know there is a general formula for converting 2nd Piola Kirchhoff stress and Green Lagrange strain to engineering stress and strain...
