✦ Synopsis

The use of simple models to study the structural dynamics and crack stability of a cracked cantilever beam subject to impact is demonstrated. A rigid-perfectly plastic material model is used, and the J-integral and tearing modulus concepts are employed in simple forms. Concise algebraic expressions provide means for validating some of the assumptions made, and they are shown to be capable of capturing the salient phenomena involved in the problem.
