Hello everyone,
I have been tried unixal buckling analyisis of composite plate( for comparasion of Ansys results). But I guess failed some reason about boundary conditions, every time. In my scneraio, plate length (a) 100 mm, width (b) 100 mm. Each ply thickness 2mm and total thickness 10 mm, sequence of laminate [0, 90, 0, 90, 0], boundray condition simply supported (ss) and force: unaxial compression 10MPa. But I can't never set up exact boundary condition. In my knowledge (probably I'm wrong) Simply supported BC means, all edges are ''0'' in cartesian coordinate (x, y, z) system.
I used ''3D wizard>Strucutral Mechanics>Layered Shell(for physic)'' path for analysis in Comsol. Maybe this path wrong!
Please help me, thanks for all for attention.
