CRACK PROPAGATION IN WEDGED DOUBLE CANTILEVERED BEAM SPECIMENS

A closed form analytical solution of crack propagation in double cantilevered beam specimens opened at a constant rate has been found. Hamilton's principle for nonconservative systems was applied to describe the crack motion, under the assumption of a Bernoulli-Euler beam. The calculations of beam motion take into account wave effects in the Bernoulli-Euler theory of elastic beams. The boundary conditions satisfied are the fixed ones of zero bending moment and constant beam opening rate at the load end of the specimen and the moving ones of zero deflection and zero slope of the deflected beam at the tip of the moving crack.
