Dynamically loaded variable thickness cantilevers using a magnetomotive impulse

Dynamical equations governing the plastic deformation of a rigid-perfectly plastic, constant-width cantilever whose cross-sectional thickness is a linear function of length, subject to impulsive tip loading, are obtained and the plastic hinge speed and root rotation are predicted.

Six experimental results are given for root rotation vs root thickness to tip thickness ratio when a constant magnetomotive tip impulse is delivered.
