Analysis of Residual Stresses Induced in Epoxy Coating I on Concrete
초록
This paper deals with the singular stresses developed in a polymer coating on concrete due to temperature change. The boundary element method is employed to investigate the behavior of interface stresses. Numerical results show that very large stress gradients are present at the interface comer and such stress singularity dominates a very small region relative to layer thickness. Since the exceedingly large stresses at the interface corner cannot be borne by coating materials, local yielding or delamination can occur in the vicinity of free surface.
