Is there any freeware solver to solve plate buckling?
I mean like this:
With constraints(all edges are pinned) and distributed compressing loads:
I need solver that provide linear buckling, NOT normal/resonant mode analysis
(well if it has normal mode analysis - it's a plus, but this is not...
I have a stiffened panel that looks like this:
This panel is under shear:
All sides of the panel are pinned. Txy - is distributed shear load.
Which constraints should I set to simulate stiffened panel under pure shear?
As for me I did this (but don't know is it good approach):
Constraints...
How quadrilateral elements represented in most FEA solvers for structural mechanics problems?
I know that Nastran-95 represent quadrilaterals for membrane and bending elements as a set of triangles:
At the same time there are a lot of literature where stiffness matrix for quadrilaterals is...
