Abstract: In some polymers, stress-induced changes in molecular mobility give rise to a strain-softening effect. The influence of this effect on the stress and deformation fields near a crack tip are ...

Abstract: The self-similar crack expansion method is developed to calculate stress intensity factors for three-dimensional cracks in an infinite medium or semi-infinite medium by the boundary integral element ...

Abstract: A direct approach for elastic-plastic analysis and shakedown is presented and its application to a two-dimensional rolling contact problem is demonstrated. The direct approach consists of an ...

Abstract: The stability and structure of shear bands and how they relate to initial imperfections is studied within the framework of a one-dimensional boundary value problem. It is shown that in ...

Abstract: Three-dimensional planar cracks under mixed-mode loading conditions are investigated by using the selfsimilar crack expansion method with the boundary integral equation technique. For a planar crack ...

Abstract: A new method, named the limit-state surface element (LSSE) method, for problems in structural reliability is presented. The method is based on discretization of the limit-state surface into a finite number of elements. ...

Abstract: Based on fiber reinforced continuum mechanics theory, an anisotropic hyperelastic constitutive model for the human annulus fibrosus is developed. A strain energy function representing the anisotropic ...

Abstract: A direct analysis method for problems in repeated elastic-plastic rolling/sliding contact is presented. The method is shown to be an efficient technique for the determination of the steady-state ...

Abstract: We describe a computer model for predicting ductile-fracture initiation and propagation. The model is based on plastic strain. Fracture starts or a crack extends when the integrated product of ...
