Note On Effect Of Elastic Deformation At The Root Of A Cantilever Beam, M.T. Liang, D.B. Chan

Journal of Marine Science and Technology

Parkes neglected elastic strains and examined a classical problem of rigid- plastic structural dynamics for finding the deformation of a cantilever beam carrying a mass at its tip which is subjected to a short pulse loading. Symonds and Fleming examined the Parkes problem by making comparison between exact numerical solutions obtained from an ABAQUS program for an elastic-plastic beam and the rigid-plastic solution slightly modified to allow for large deformation. Further observation is acquired by comparision also with a simplified elastic-plastic approach based on treatment of elastic and plastic action in artificially separated stages. and Yu examined the Parkes problem …
