Abstract

Experimental tensile-compressive cyclic tests on DEN-concrete specimens reveal several phe- nomena: nonlinear elasticity, stiffness reduction, stiffness recovery, permanent deformation and hysteretic behavior, which changes shape during tensile unloading to compressive loading. In this paper, a constitutive model is proposed that captures all these effects, and which is based on strain decomposition into a classical linear elastic strain and a non-classical strain described by the Preisach-Mayergoyz model (PM-model).
