Large Viscoplastic Deflections of Impulsively Loaded Plane Frames.
Abstract
Applications are described of two estimation techniques to obtain final deflections and response times of plane rectangular frames subjected to impulsive loading on the transverse (beam) member. Deflections up to roughly one third the span (thirty thicknesses) are estimated by the mode approximation and deflection bounds techniques, treating the plastic rate dependence by means of homogeneous viscous constitutive equations. Comparisons are made with recent test results, and the degree of agreement is discussed in terms of the known error sources of the two techniques. (Author)
