Ratcheting crystal plasticity modeling in microstructure of magnesium alloy under stress-controlled cyclic tensile loading with non-zero mean stress

Todays, the requirement of lowering the vehicle weight for the reduction of the fuel consumption and emissions, one of the methods considered by designers is to use the ligh magnesium alloy under cylclic loadings. In this article, considering the microstructure of the AZ91D magnesium alloy, its crystalline structure, a model for predicting the ratcheting behavior of this alloy was adapted and v...

Regulation of Kir2.1 Function Under Shear Stress and Cholesterol Loading

L ining the innermost layer of blood vessels, the endothelium is in direct contact with circulating blood elements and, consequently, is affected by mechanical forces generated by blood flow. Among these forces, fluid shear stress site-specifically regulates endothelial cells (ECs): In regions where the flowing blood is multidirectional (low shear stress or disturbed flow), ECs are activated an...

Shallow Caps under Pressure Distributions* Finite Polar Dimpling of Sub-buckling Axisymmetric

For shallow caps under an axisymmetric external pressure distribution which is inward (with a representative magnitude pO) in a neighborhood of the pole and outward away from the pole, it has been shown previously that a finite axisymmetric dimple state of deformation is possible if p0 is at least of the order of the classical buckling pressure for a complete spherical shell, Pi, and that, asym...
