Loading a specimen as shown in Figure 1a produces shear stresses in the material. An initially square element of the material, having vertical sides parallel to the direction of loading, is distorted by these stresses into a diamond shape as illustrated in Figure 1b, where the distortion is greatly exaggerated for pictorial clarity. Shear strain is defined as the magnitude of the change in the ...

micropolar plasticity provides the capability to carry out post-failure simulations of geo-structures due to microstructural considerations and embedded length scale in its formulation. an essential part of the numerical implementation of a micropolar plasticity model is the integration of the rate constitutive equations. efficiency and robustness of the implementation hinge on the type of inte...

A finite element program capable of analysing finite plane strain deformations of incompressible rubberlike (Mooney-Rivlin) materials has been develop~d. Two problems, namely a long wall loaded uniformly in two directions and a thick-wall cylindrical pressure vessel loaded internally, have been solved. The computed values of displacements, strains, stresses and hydrostatic pressure agree very c...

The strain dependence of the apparent activation energy desorption H2O on epitaxial, TiO2-terminated, out-of-plane polarized, BaTiO3(100) thin films has been investigated using X-ray diffraction, photoelectron spectroscopy and temperature-programmed desorption. increases significantly with in-plane strain, suggesting that strain-induced ferroelectric distortion determines strength chemical bond...
