AN ANARITICAL STUDY ON SINGULAR STRESS FIELDS AT THE EDGES OF INTERFACES OF FINISHINGS BY INTERFACIAL FRACTURE MECHANICS : A case study of compression tests of units composed of concrete bodies and cementicious adhesive mortar with ceramic tiles

Abstract

This paper describes analytical results by a boundary element method on stress singular conditions at the interface edges between the concrete bodies and cemeticious adhesive mortar with ceramic tiles. A general stress function is also presented that uses two singularity parameters to predict shear stresses near the stress singular points by a fracture mechanical method. Several new methods are presented to obtain the values of two parameters which are stress intensity factors and singularity exponents. Furthermore, the usefulness of these methods and the characteristics of the two parameters under different influences of several kinds of finishing conditions are discussed.
