Steady-state transport analysis

A steady-state transport analysis:

  • allows for steady-state rolling and sliding solutions including frictional effects and inertia effects;

  • allows for steady-state solutions to be obtained directly or by using a quasi-steady-state (pass-by-pass) technique;

  • is used to model the interaction between a deformable rolling object and one or more flat, convex, or concave surfaces;

  • is based on a specialized analysis capability where the rigid body motion is described in a spatial or Eulerian manner and the deformation in a material or Lagrangian manner;

  • allows for one element set in a model to be described in an Eulerian manner while the rest of the elements in the model are treated in a classical Lagrangian manner;

  • can be preceded by a static stress analysis or followed by a natural frequency extraction or a complex eigenvalue extraction step;

  • uses regular stress/displacement elements and special steady-state rolling and sliding contact pairs;

  • is currently available only for three-dimensional analysis with an axisymmetric geometry or a periodic geometry; and

  • allows rate-independent, rate-dependent, or history-dependent material behavior.
