Dear All,

 

How much importance to calculate the vonmises stress along with corner stress data???

 

Whether it is mandatory ??

 

Without it , if we calculate the vonmises stress is reliable or not??

 

Thanks

RAM

    Hi Ram,

    There is a description of corner data, its significance and use in the HyperWorks student guide (Practical Aspects of Finite Element Simulation). In page 187 of the student guide,  we see an example about stress concentration in a plate with a hole, which is a good example where corner stress results are necessary.
    By default the element stresses for shell (and solid elements) are output at the element center only. In other words, these stresses are not exactly the ones “existing” at the hole. To better resolve the stresses at the hole, the element stresses are output at the grid points using bilinear extrapolation (in HyperMesh activate the Control cards > Global output request > Stress >Location: Corner).
