Plane motions of elastic pseudo-rigid bodies: An example (Q1310251)

The paper discusses a theory of pseudo-rigid bodies developed largely by the first author [see the first author and \textit{R. G. Muncaster}, The theory of pseudo-rigid bodies (1988; Zbl 0687.70001)]. It is a model approximating the theory of finite elastodynamics. The authors consider the motion of a pseudo-rigid disk between two smooth, rigid, parallel planes. A focus of the study is the reponse to impulses. It is shown that an inextensibility condition produces smooth, as opposed to singular, motion reversals. The paper is brief, but well written. It should be of interest and use to researchers in elasticity theory.
