Abstract

Abstract

Based on the(Ⅱ) of the present work,the behavior of shear beam model at crack initiation stage and at instable propagation stage was studied.The prime results include:1) discriminant equation which clarifies the mode of instability,snap-back or snap-through,was established; 2) analytical solution was given out for the double shear beam and the load-displacement diagram for monotonic loading was presented for a full process; and 3) the problem of the energy release induced by instability was discussed.
