Abstract

We present identification analysis of order of singularity around singular point of bonded structure using displacement values. The finite element and the adjoint variable methods are employed for the identification of the order of singularity. In addition, the Akin's singular element is introduced in the deformation analysis of the bonded structure model. The steepest descent method is applied to identify the order of singularity.
