    Is there any freeware solver to solve plate buckling?

    Thanks everyone.

    Is there any freeware solver to solve plate buckling?

    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...

    Which constraints should I set to simulate stiffened panel under pure shear?

    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?

    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...
