Through reading nonlinear material models in ANSYS manual, I found one wrong reference, and some important references were not given. What this shows me is how much blind faith we have in the CAE software now that very few bother to check and try to understand the theory behind it any more.
Applying wind load using 3-D Structural Surface Effect in ANSYS Classic (APDL) – SURF154 elements.
This trend has been going on for a few years – most major 3D CAD software entered into marriages with some FEA software and created a “one stop bundled solution” for the users. This should be a good thing. Why not? What can a better suited marriage than this? Don’t FEA models all start with…
Inertia load such as centrifugal load is one of the dominant loads in rotating equipment. When the rotating speed is high, it may be THE dominant load. Can it be simplified as a uniformly distributed load? What are things we must aware when we do the simplifications? This blog discuss this topic by giving an example of a fan blade study.
