A parametric study approach evaluating drained/undrained behavior of sand has been developed as a simple/quick hypo-elastic model capable of being used in engineering applications. The volumetric interaction of sand grains behavior against pore water pressure induces the tendency of soil mass volume change to contract/dilate due to variation of effective mean stress on solid grain, pore water p...

responses of twenty chickpea genotypes to drought stress were evaluated in the farm of college of agricultutre, razi university, kermanshah, iran in 2006-2007. the experiment was carried out in randomized complete block design with three replications under two water stress and non-stress conditions. the results showed significant differences among the genotypes for most of the traits. maximum y...

Granite residual soil is one of the most frequently encountered problem soils in tropical regions, whose mechanical behavior heavily depends on pattern variation mean effective stress (p’) during shearing, which can be classified into three categories: increasing-p’, constant-p’, and decreasing-p’. Unfortunately, so far, stress–strain strength characteristics granite have been studied mainly un...

A variational formulation of small strain ductile fracture, based on a phase-field modeling crack propagation, is proposed. The an effective stress description gradient plasticity, combined with AT1 model. Starting from established statements finite-step elastoplasticity for generalized standard materials, mixed statement consistently derived, incorporating in rigorous way update both the elast...

Abstract We provide theoretical investigations and empirical evidence that the effective stresses in computational homogenization of inelastic materials converge with a higher rate than local solution fields. Due to complexity industrial‐scale microstructures, methods often utilize rather crude approximation microstructure, favoring regular grids over accurate boundary representations. As accur...
