Hi all,
I am attempting to model an artery under internal pressure in ANSYS APDL.. This is my current attempt.. select solid 8 node 183 element type (and specify thickness) select 5 parameter Mooney-Rivlin (for which I have constants) create quarter area model dimensions map mesh with quad area elements Apply symmetry Boundary Conditions to artery inner cut lines Apply pressure load on internal area line Activate large deformation (NLGEOM,ON) Solve using static analysis This approach works fine for linear-elastic materials, but I cannot understand why it yields no results in this situation???? ANY ADVICE?? Thanks in advance |
