Axisymmetric thermoelasticity by combined boundary and finite elements

Abstract

The boundary element and finite element methods have been combined so as to allow for arbitrary intermixing of element types in modelling problems of axisymmetric thermoelasticity, including body forces due to rotational inertia. The formulation for combining the methods is given, and a general purpose, finite element program has been generalized to accommodate both types of elements and to determine stresses within and on the boundary of boundary‐type elements after the primary solution for the displacements. Example problems demonstrate the validity and accuracy of the technique.
