Poisson of bedding mortar under multi-axial stress conditions
Mohamad, Gihad; Lourenço, Paulo B.; Roman, Humberto R.; Rizzatti, Eduardo; Sartori, TatianeThe main goal of this work is the understanding of triaxial compression capacity of bedding mortar. It was observed by the experimental tests that the behavior of the stress and strain response is highly nonlinear and depends on the increase of lateral stress. In all studies presented here, the ultimate strength envelope of triaxial mortar can be represented by a linear function with similar angular coefficient...
Numerical simulation of concrete block masonry under compression
Mohamad, Gihad; Lourenço, Paulo B.; Roman, Humberto R.; Rizzatti, Eduardo; Sartori, TatianeThe main goal of this work is evaluate numerical model to reproduce the compression test of concrete block prisms, through a constitutive model of materials using the theory of plasticity and compare its results with experimental tests to preview the stress, strain and failure mode of the masonry. The post peak behavior of the material under tensile followed an exponential law and, under compression, a paraboli...
