Abstract
The paper presents an application of Boundary Element Method (BEM)-based technique to the estimation of multidimensional, spatially and temporarily highly-varied, boundary conditions in thermoelasticity problems. The BEM is employed for numerically effective and accurate calculation of sensitivity coefficients. The set of sensitivity/constraints equations is solved employing the derived algorithm with regularization inherent via covariance matrices a priori, and combined with function specification approach (piece-wise linear approximation of time variation).
