For what , the elasticity references use galerkin potential vector to solve the kelvin problem, but not use directly in boussinesque problem and add the westergaard potential function? I'm not seen any result in reference books.
I want make a model of acoustic-solid interaction (an acoustic wave made by vibrating solid). But because of time consumption, i don't need structure analysis and it's better to model solid as a...

Hi, when i plot the time dependent plot of a selected point of a beam (for example in w displacement), the resulted plot was true but it is not smooth enough as i expect it. i try to decrease time...

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...
