Summary
The boundary integral equations pertaining to the whole or a portion of an axi-symmetric solid are converted to finite-element-type equations and subsequently assembled into the system stiffness equations along with similar boundary-type elements or axi-symmetric finite elements. The algorithms for incorporating a mixture of both element types were developed and merged into a standard finite element program. The method was implemented so that the usual linear and quadratic finite elements can be arbitrarily intermixed with general shaped, boundary-integral, formulated elements, including exterior or infinite elements. The thermoelastic stresses may be determined within all element types and on the periphery of the boundary elements.
