MIXED MODE CRACK PROPAGATION IN CONCRETE UNDER UNIAXIAL COMPRESSIVE LOADING. FRACTURE OF CONCRETE AND ROCK: RECENT DEVELOPMENTS. PAPERS PRESENTED AT THE INTERNATIONAL CONFERENCE, UNIVERSITY OF WALES, COLLEGE OF CARDIFF, SCHOOL OF ENGINEERING, SEPTEMBER 20-22, 1989

Mixed mode crack initiation and propagation starting from the aggregate-matrix interface in concrete under uniaxial compression were studied. During the experiments, it was possible to observe crack initiations, crack extensions, and to obtain load versus crack extension curves and main crack tip displacements. Crack angles and normalized initiation stress at crack initiation were predicted and compared with experimental results. A finite element program with quarter-point singular tip element was used to calculate SIFs, crack faces and main crack tip displacements for different inclinations and extensions of propagating cracks. The finite element method (FEM) calculated main tip displacements were compared with those measured experimentally. Based on these a modified linear elastic fracture mechanics (LEFM) model is proposed.(A) For the covering abstract of the conference see IRRD 829348.
