Hello, I am implementing a simple test of a cylinder with fixed extremities under pressure (length of 42 mm, radius of 2.5 mm and thickness of 0.6 mm). Material has a Young's modulus of 0.6 MPa and nu=0.45. I tested ShellBST, ShellReissner and ShellANCF4234 in chrono and compared the results with Abaqus.
With a pressure of 0.001 MPa, the results are the same as Abaqus. However, when increasing the pressure to 0.03 MPa, the deformation of the cylinder is roughly twice lower in chrono than in Abaqus (results are in the same magnitude for all 3 shell elements). To completed the analysis, in Abaqus, when setting the NLGEOM parameter to NO, the deformation goes down to the range of chrono deformation. My question then : are there shelle elements able to consider large deformations ? Did I forget a hidden parameter somewhere ? Thanks a lot for you help, Solenne -- You received this message because you are subscribed to the Google Groups "ProjectChrono" group.
