patch test finite element????
patch test finite element????
(OP)
Hi everyone,
I am trying to do a patch test through describe the displacement which called ''The Displacement Test''. The idea to study a small area from whole the geometry and see how is working. I wonder if someone has a simple example in FEMAP about that ??? I attach a file about patch test which I got it from the internet.

eg start with a square quad, apply axial load ... should work out well
now a rectangular element ... it'll work out less well
then a trapezoid ... less well again.
then same again with bending moment applied ...
etc

Like rb1957 says, patch test is a method to test a single element and how good the element formulation is. If I remenber correct, to perform it on a mesh (several elements) is theretically possible but very impractical.
