The sclera is the white outer shell and principal load-bearing tissue of the eye as it sustains the intraocular pressure. We have hypothesized that the mechanical properties of the posterior sclera play a significant role in and are altered by the development of glaucoma-an ocular disease manifested by structural damage to the optic nerve head. An anisotropic hyperelastic constitutive model is ...

Image restoration has been an active research area. Dierent formulations are eective in high qualityrecovery. Partial Dierential Equations (PDEs) have become an important tool in image processingand analysis. One of the earliest models based on PDEs is Perona-Malik model that is a kindof anisotropic diusion (ANDI) lter. Anisotropic diusion lter has become a valuable tool indierent elds of image...

the capability of sand constitutive models is remarkably improved by taking into account the effect of soil state in their formulations. in this study, it has been shown that considering the effect of soil state leads to better simulation of soil instability of shear banding type. to this aim, constitutive equations of a state dependent sand model are explained first. consequently, the general ...

Many soft biological tissues have the important task of transmitting necessary forces to control movements, hold organs in place or ensure a relatively continuous flow of fluids. Examples of these tissues are ligaments, tendons, skin and blood vessels. Biological tissues can be seen as composite materials whose constituents are assembled into a hierarchical structure. At a macroscopic structura...

The deformation and fracture of the high strength steel which is used to fabricate grade X100 steel pipe were investigated at room temperature, on plate and pipe. Anisotropic behaviour was characterized by using tensile tests conducted along different directions. The fracture toughness of plate and pipe materials are compared using compact tension (CT) and Charpy V-notched tests. In both cases,...

Extended Einstein-Maxwell model and its application to the problem of evolution of magnetized Bianchi-I Universe are considered. The evolution of medium magnetization is governed by a relaxation type extended constitutive equation. The series of exact solutions to the extended master equations is obtained and discussed. The anisotropic expansion of the Bianchi-I Universe is shown to become non-...
