October 26, 2020 at 3:49 pmKaiAnsys EmployeeHi, principal stress and normal stress are different. They are only the same in certain conditions such as simple tension. You may google principal stress to find out more details on how principal stress is calculated.n
October 27, 2020 at 4:14 amHarsihilZLHZSubscriberIn cauchy stress tensor, sigma_11,sigma_22,sigma_33 are the principal stress and sigma_12,sigma_13,sigma_21,sigma_23,sigma_31,sigma_32 are the shear stress is correct ?nI am confused between Principal stress and Normal stress (shows in Workbench)nAny link or formulation can anyone share?.
October 28, 2020 at 3:50 pmKaiAnsys Employeesigma11, sigma22, sigma33 are normal stress, they are calculated in global coordinate system. They are only equal to principal stress if you do coordinate transformation so that shear stress are zero in the stress tensor. As Ansys employee, I'm not allowed paste any third party link here, but you can find how to transform by googling stress tensor to principal stressn
