Explicit dynamic analysis

An explicit dynamic analysis:

  • is computationally efficient for the analysis of large models with relatively short dynamic response times and for the analysis of extremely discontinuous events or processes;

  • allows for the definition of very general contact conditions (About contact interactions);

  • uses a consistent, large-deformation theory—models can undergo large rotations and large deformation;

  • can use a geometrically linear deformation theory—strains and rotations are assumed to be small (see Defining an analysis);

  • can be used to perform an adiabatic stress analysis if inelastic dissipation is expected to generate heat in the material (see Adiabatic analysis);

  • can be used to perform quasi-static analyses with complicated contact conditions; and

  • allows for either automatic or fixed time incrementation to be used—by default, Abaqus/Explicit uses automatic time incrementation with the global time estimator.
