A multi-scale approach is devoted to the analysis of hygro-elastic internal stresses in porous composite materials. Voids in composite materials are known to cause a significant reduction of mechanical properties. Moreover, in a humid environment they also affect the moisture absorption and the induced internal stresses. In this work, a self-consistent approach is used to estimate internal stre...

gamma aminobutyrate (gaba) is a non-protein amino acid that is thought to play an important role in the modulation of the central response to stress. mechanisms by which gaba may facilitate these responses to stress are metabolic and/or mechanical disruptions. environmental stresses increase gaba accumulation through cytosolic acidification, induce an acidic ph-dependent activation of glutamate...

In this paper, an analytical method is developed to obtain the solution for the one dimensional transient thermal and mechanical stresses in a hollow cylinder made of functionally graded material (FGM) and piezoelectric layers. The FGM properties are assumed to depend on the variable r and they are expressed as power functions of r but the Poisson’s ratio is assumed to be constant. Transient te...

Fiber suspension theory model parameters for use in the simulation of fiber orientation in complex flows are, in general, either calculated from theory or fit to experimentally determined fiber orientation generated in processing flows. Transient stress growth measurements in startup of shear flow and flow reversal in the shear rate range, γ = 1 to 10 s, were performed on a commercially availab...
