Abstract: In materials with a strain‐softening characteristic behavior, classical continuum mechanics favors uncontrolled strain localization in numerical analyses. Several methods have been proposed to regularize the problem. Two ...

Abstract: This paper deals with the application of continuum damage mechanics to the description of the response of reinforced concrete members. Two simplifying assumptions are made: (1) The constitutive law of concrete is the ...

Abstract: This paper presents a model capable of providing estimates of the apparent permeability directly from the pore-size distribution and from the properties of the fluid to be considered. The model is based on a hierarchical ...

Abstract: A recent nonlocal damage formulation, in which the spatially averaged quantity was the energy dissipated due to strain-softening, is extended to a more general form in which the strain remains ...

Abstract: The purpose of this article is to describe a tool developed in order to equip a finite-element software based on nonlinear beam analysis with an error indicator aimed at measuring discretization errors. The technique is ...

Abstract: This paper considers a model of crack propagation taking place at the interface between a rigid support and an elastic plate. The interface is modeled using a fiber bundle model (i.e., describing a damage behavior using a ...

Abstract: In the usual local finite element analysis, strain softening causes spurious mesh sensitivity and incorrect convergence when the element is refined to vanishing size. In a previous continuum formulation, these incorrect ...

Abstract: The characteristic length of a heterogeneous brittle material such as concrete represents a material property that governs the minimum possible width of a zone of strain‐softening damage in nonlocal continuum formulations ...

Abstract: Experimental tests exhibit a strong interaction between material damage and transport properties of concrete. There are at least two asymptotic cases where some theoretical modeling exists: in the case of diffuse cracking, ...
