I wants to perform modal analysis of a body present in a viscoelastic medium

    • Hassan_AUT1991

      The spherical shell body is present in a viscoelastic medium; what type of contacts and elements I shall use between the medium and spherical body. (I am trying to simulate a biological environment)

      The body also contains fluid within; what type of contact I shall define between the body and fluid within?

      Kind regards

      Hi Modal analysis is alinear analysisso we can not include nonlinearities (large deflections, contacts (frictional), and material nonlinearities). We can ofcourse include large deflections (geom. nonlin.) in a static analysis (and of course plasticity and frictional contacts), but not in modal.
      The viscoelastic model is used when the large-deflection effects are active (NLGEOM,ON).
      I suggest you look at this forum discussion modal analysis for structures under water considering p-delta effect (large deformation/deflection) ÔÇö Ansys Learning Forum
