Abstract
In engineering practice, analysis of interfacial thermal stresses in composites is
a crucial task for assuring structural integrity when sever environmental temperature
changes under operations. In this article, the directly transformed boundary integrals
presented previously for treating generally anisotropic thermoelasticity in two-dimension
are fully regularized by a semi-analytical approach for modeling thin multi-layers of
anisotropic/isotropic composites, subjected to general thermal loads with boundary
conditions prescribed. In this process, an additional difficulty, not reported in the
literature, arises due to rapid fluctuation of an integrand in the directly transformed
boundary integral equation. In conventional analysis, thin adhesives are usually neglected
due to modeling difficulties. A major concern arises regarding the modeling error caused
by such negligence of the thin adhesives. For investigating the effect of the thin adhesives
considered, the regularized integral equation is applied for analyzing interfacial stresses
in multiply bonded composites when thin adhesives are considered. Since all integrals are
completely regularized, very accurate integration values can be still obtained no matter
how the source point is close to the integration element. Comparisons are made for some
examples when the thin adhesives are considered or neglected. Truly, this regularization
task has laid sound fundamentals for the boundary element method to efficiently analyze
the interfacial thermal stresses in 2D thin multiply bonded anisotropic composites.
