A combined boundary element / finite element method (BEM/FEM) in the time
domain is developed and applied for solving two-dimensional dynamic
The BEM is used for the portion of the structural
domain expected to remain elastic, while the FEM for the remaining expected
to become elastoplastic during the deformation history.
Thus, while an interior
discretization is required for the FEM domain, only a boundary discretization
is necessary for the BEM domain with obvious gains in efficiency.
methods are coupled together at their interface through equilibrium and
The solution procedure is based on a step-by-step ti...
