Collisions and fracture : a l-D theory : how to tear off a chandelier from the ceiling / E. Bonetti, M. Frémond. - In: JOURNAL OF ELASTICITY. - ISSN 0374-3535. - 74:1(2004), pp. 47-66.
Abstract:
When a plate falls on the ground, it breaks. We study this phenomenon at the macroscopic level. We restrict ourselves to 1-D problems and illustrate the theory with a chandelier to which a falling stone is tied. The collisions are assumed instantaneous. Percussions are introduced at the unknown fracture points. Equations of motion and constitutive laws give a set of differential equations, whose corresponding variational problem may be solved in SBV (special functions of bounded variation). The example shows how the theory applies and gives realistic results.
