Hello sci.engr.mech group,
I'm an electrical engineering student working in MEMS modeling analysis using the ANSYS Multiphysics/LS-DYNA software for verification of our simulations. Currently I'm modeling a plate/shell element based on J.S. Przemieniecki's "Theory of Martrix Structural Analysis". I've done a simple analysis of a single plate/shell element with 4 nodes. I've constrained 3 of the 4 nodes and applied a
1uN force in the z-direction on the unconstrained node. I'm happy with the results compared to the matrix model we've created in the UZ displacement, but I'm trying to determine what units are used when the output from ANSYS displays ROTX, ROTY, and ROTZ. Are these in units of radians? If so, is the radian angle taken from the center of the element? My matrix results are not converted to radians and I'm trying to find some way to convert my results to see if they match or are close to ANSYS. Hopefully I'm not too confusing in my question.
Thanks very much,
