Abstract: The deformation and crack width in concrete walls of slabs, plates, panels, and shells reinforced by a regular rectangular net of steel bars and subjected to in‐plane (membrane) internal forces is analyzed taking into ...

Abstract: The spacing and width of cracks in a parallel crack system is approximately analyzed using the energy criterion of fracture mechanics as well as the strength criterion. The energy criterion indicates that the crack spacing ...

Abstract: In a companion paper by Bazant and Oh, a simplified theory for predicting the spacing of cracks in a parallel crack system in reinforced concrete was presented. In this paper a different approximate analysis yields about ...

Abstract: A constitutive model for a brittle aggregate material that undergoes progressive tensile fracturing or damage is presented. It is assumed that the normal stress on a plane of any orientation within the material, called the ...

Abstract: The fracture of rock is assumed to arise from propagation of a blunt crack band with continuously distributed (smeared) microcracks or continuous cracks. This approach, justified by material heterogeneity, is convenient ...
