Terms of service of the steels with retained austenite in the microstructure, is severely depended on the stability of austenite during the course of deformation. The present work aims to evaluate the mechanical stability of austenite in nanostructured, carbide free bainitic steels during tensile testing and cold rolling process. To achieve the microstructure with retained austenite, the steel ...

Arteries are modeled, within the framework of nonlinear elasticity, as incompressible two-layer cylindrical structures that are residually stressed through differential growth. These structures are loaded by an axial force, internal pressure and have nonlinear, anisotropic, hyperelastic response to stresses. Parameters for this model are directly related to experimental observations. The possib...

The classification of materials into insulators and conductors has been shaken up by the discovery of topological insulators that conduct robustly at the edge but not in the bulk. In mechanics, designating a material as insulating or conducting amounts to asking if it is rigid or floppy. Although mechanical structures that display topological floppy modes have been proposed, they are all vulner...

Practical applications of conducting polymers such as polyaniline as membranes are particulary limitedbecause of their poor mechanical properties. However by mixing polyaniline with some conventional insulatingpolymers such as nylon and preparation composite films through solvent casting or blending, it seems to be asuitable way in order to increase the mechanical properties of the conducting p...

finding a suitable estimation of stability domain around stable equilibrium points is an important issue in the study of nonlinear dynamical systems. this paper intends to apply a set of analytical-numerical methods to estimate the region of attraction for autonomous nonlinear systems. in mechanical and structural engineering, autonomous systems could be found in large deformation problems or c...

INTRODUCTION: The initial mechanical stability of cementless implants is critical to achieve successful osseointegration through minimization of deleterious micromotion. Controversy exists regarding the most reliable and appropriate methodology for in vitro mechanical testing of implants used to guide design and performance of cementless total knee replacement. Mechanical testing methods vary w...
