STUDY OF SHEAR FRACTURE. 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

A series of tests carried out on symmetrically notched mortar cubes were conducted in order to study the direction of crack propagation due to a combination of loads generating a concentrated shear force zone. The test results indicated that shear fracture can be generated in specimens having shear stresses concentrated within a narrow shear zone. It was observed that in certain cases the direction of microfissures appearing between the notches followed fairly closely the direction of maximum shear stresses which was estimated from the elastic stress analysis. The combination of visual observation, still photography and cine camera techniques was used to record the development of critical stages of a shear fracture zone. Fracture specimens and loading were simple, producing near pure shear state of stresses at the notch tips.(A) For the covering abstract of the conference see IRRD 829348.
