Abstract : A review is given of earlier work on the plastic response to impulsive loading of a beam clamped against end rotation and axial displacements, taking account of small finite transverse displacements and ofstrain rate dependence of the yield stress. New solutions are derived from rigid-plastic analysis which include both effects in simple approximate ways. Deflections are compared as obtained from these formulas, from experiments described here on mild steel beams, and from finite-difference numerical solutions using the M. I. T. rod model with elastic-plastic strain rate sensitive behavior. The significance of agreements observed is discussed. (Author)
