Linear Analysis of the Constitutive Relation of Concrete Elastoplastic Disturbance

Abstract:

A linearization method of the uniaxial non-fitting nonlinear stress-strain curve given by the author of the paper is presented. The evolution equation between disturbances variable and plastic strain is derived based on Theory of Duality Disturbance. A simple method for concrete structures preforming elastoplastic analysis is presented (including softening analysis).
