A GENERALIZATION OFNONAKA'S SHEAR HINGE SOLUTION TO RIGID-PLASTIC HARDENING BEAMS UNDER IMPULSIVE LOADING

摘要

Nonaka's shear deflection failure solution for a rigid, perfectly plastic beam is generalised to predict multi-modes of shear failure for a rigid-linear hardening plastic beam under impulsive loading by using a travelling plastic shear hinge model. The conditions for the different modes of shear failure, i. e., excess deflection failure, excess shear strain failure and adiabatic shear failure, and their relations, are analyzed.
