hello,everyone I just want to know how could I get the direction or angle of principal stress, as it show in the tensor plot. I have been struggling with this problem since yesterday, but I didn't get anything. Thank you for you time..so..much.. Any advice will be appreciated.
Hello, I have corroborated that Von Mises STRESS is output considering this formula, with principal stresses What formula does hypermesh uses for strain? Thank you!
Dear All, I have a structure for which i have carried out frequency response analysis using Hypermesh as preprocessor and NASTRAN as solver. I have the following queries: 1) In the .f06 output file, the principal stresses are not printed. 2) I have used hex hedral meshing for the entire structure. After carrying out the meshing and frequency response analysis only Normal shear stress are printed. When i use the formula(see attachment) to calculate 3d principal stresses, at some points, i am unable to calculate the angle due to incorrect value? Is this due to inaccurate meshing? Please advise.
