On Volterra Dislocations of Finitely Deforming Continua

Department of Mechanical Engineering, University of California, Berkeley, CA 94720-1 740, USA

In the context of finite deformations, a purely kinematical treatment of Volterra dislocations is presented. These dislocations correspond to deformations that have a jump discontinuity across a singular surface in a fixed reference configuration of the continuum, but whose right Cauchy-Green deformation tensor field is continuous and has second partial derivatives that are continuous. Analytical and geometrical proofs of Weingarten's theorem for finite deformations are given. Tune-dependent Volterra dislocations are also considered.

Key Words: Volterra dislocations • discontinuous displacements • surfaces of discontinuity • multiply connected continua
