How I get directional principal stress in Workbench. I am able to find maximum principal stress, minimum and middle so on. But I want to get result at directional. I want to select direction.

for example this;

Hi,nIf you want to get normal stress in a certain direction, you can define a local coordinate system with one of the axes (say x-axis) aligned with the the direction in which you want the normal stress. Then insert a Normal Stress result and under coordinate system, choose the local coordinate system.nHope this helps,nSainn

nnYou can plot the vector principal stress plot and export the result (.xls file) which will give you the angles required to produce a coordinate system whose X, Y and Z-axis are the directions of maximum, middle and minimum principal quantities.nnnRegards,nAshish Khemkan

Thank you. But Ashish, I neet contour graphic for principal stress. Xls is not useful for me. nIn mechanical Apdl has this result {preferences/data and file opts,results summary /deformed shape/nodal solution and then DOF solution, stress/1st principal stress/.......} I search corresponding version in workbench for principal stress at x direction, sigma 1 and sigma 2 (y direction) and so on n

Okey, we don't solve this problem. But this result already exist in APDL. ( {preferences/data and file opts,results summary /deformed shape/nodal solution and then DOF solution, stress/1st principal stress/.......}nI need 1 st principal stress. How I get result in workbench?nWhat is the APDL result command about 1 st prinpial stress?n
