Abaqus FEA Scripting with python - if curious: then learn in the Property Module which Element Type is Continuum Shell, made of 8 plies of the created material.Each ply thickness is t=0,175 mm (express this value in meters to be coherent with other measurements in ABAQUS) and the orientation angles sequence is 0, 90, 45, -45, -45, 45, 90, 0. Shell-to-solid couplings, on the other hand, take account of the shell's thickness, even when it is joined to the solid along its edge. Instead of simply tying local nodes together, Abaqus assembles constraints that couple the displacement and rotation of each shell node to the average displacement and rotation of the solid surface in the vicinity of the shell node.The stacking direction of the continuum shell elements should be considered before meshing. You can also take advantage of symmetry and rotational / cyclic sysmmetry boundary conditions.
