摘要：

The kinematics of elastoplastic bodies at finite strain based on the multiplicative decomposition of the deformation gradient is developed taking into account the motion of continuously distributed dislocations. In comparison with the macro-theories of finite elastoplasticity additional degrees of freedom are introduced through Cartan's torsion having the physical meaning of the dislocation density. The set of balance equations has to be enlarged to account also for the internal motion of dislocations. Constitutive equations for such bodies are proposed inconsistency with the entropy production inequality. Copyright (C) 1996 Elsevier Science Ltd
