Abstract: One of the open questions is the performance of rate-independent versus rate-dependent constitutive formulations when failure is evaluated at the material and the finite-element levels. In the case of rate-independent ...

Abstract: A constitutive formulation is presented that covers the triaxial load‐response spectrum of plain concrete in tension as well as in shear. The elastoplastic concrete model resorts to an isotropic‐hardening description of ...

Abstract: In this paper, we examine the interaction of thermal and mechanical damage processes in heterogeneous materials such as concrete. After a brief introduction of high temperature effects in concrete, we address two topics: ...

Abstract: The present paper extends the results of discontinuous bifurcation analysis of elastoplastic solids to materials that exhibit elastic degradation. As a starting point, the concepts of elastic degradation are formulated in ...

Abstract: Corrosion is one of the most critical problems that impair the durability of RC structures. Both carbonation-induced and chloride-induced corrosion widely prevail in civil infrastructure around the globe. Expansive products ...

Abstract: The smeared-crack approach of strain-softening is a popular engineering concept for the numerical simulation of tensile failure processes in concrete and rock. Despite numerous publications on the equivalent constitutive ...
