Elastic-Plastic Theory at Finite Strain.
Abstract
It is shown that in order to solve certain technological problems, it is necessary to develop elastic-plastic theory for which both components of strain can be finite. This poses a challenging problem because of the need to include nonlinear discontinuous response to loading history, that is to determine nonlinear discontinuous functionals. Various approaches to this challenge are considered and contrasted. The possible advantages of direct extension of classical approaches is expressed. Questions of the validity and applicability of suggested theories are considered from the standpoints of invariance, convenience of representation for specific materials and for introduction into stress and strain analysis evaluations. Thermodynamic aspects are also discussed. (Author)
