Hypersingular formulation for boundary stress evaluation revisited. Part 2: Corners.

Alberto Salvadori

Abstract


This work focuses on the use of the hypersingular boundary integral equation
to evaluate the linear elastic stress tensor on the boundary. A companion
paper [1] has been devoted to smooth boundaries: in the present work, the
traction equation is analyzed at a corner, in the presence of a Lipschitz
boundary. Properties of the hypersingular and of the strongly singular operator
are discussed together with properties of the whole linear elastic integral
operator.

Keywords


Hypersingular boundary integral equations; stress evaluation; free terms; boundary element method
