Abstract

In this paper the Tangent Derivative Boundary Integral Equations (TDBIEs) are used to implement an efficient formulation for the computation of stresses and error indicators in two-dimensional, steady-state, thermoelastic problems. The ba- sis for this work is a global reanalysis technique in which, as a post-processing activity, the functional representation for the displacements is changed from La- grangian to Hermite. The new unknowns introduced in the model, namely the tangential derivatives of the displacements, are obtained by solving a second sys- tem of equations generated by collocating the TDBIEs at the functional nodes of the Lagrangian elements. This approach provides more accurate val
