Abstract: The strain failure criterion proposed by the second author is applied to obtain general solutions for the angled elliptic notch problem subject to uniform biaxial loading. The solutions can be ...

Abstract: In this paper we have used the endochronic theory of plasticity to model one of the most complex phenomena of mechanical behavior of materials, that of cyclic creep and relaxation. We have ...

Abstract: The cyclic hardening behavior of metallic materials at a prescribed constant plastic strain rate is investigated. The development is within the framework of the endochronic theory of viscoplasticity. ...

Abstract: An explicit function of material parameter β1 is proposed to accommodate the strain-rate effect in the endochronic theory of viscoplasticity developed by Valanis. The strain-rate effects are ...

Abstract: The strain failure criterion previously proposed by the first author is applied to obtain solutions for the angled elliptic notch problem subject to compressive and tensile loads. The theory ...

Abstract: For the purpose of fatigue reliability assessment based on strain-life analysis, a family of reliability-defined ε-Nf curves, called R -ε-Nf curves, is constructed by considering the interference ...

Abstract: Polymethylmethacrylate (PMMA) plates with angled elliptic notch are experimentally investigated under monotonic tension. The major interests of this investigation are the direction of crack initiation ...

Abstract: In the modeling of microstructural damage mechanisms of composites, damage evolution plays an important role and has significant effects on the overall nonlinear behavior of composites. In this ...

Abstract: Fiber reinforcement can effectively improve the toughness, shrinkage, and durability characteristics of concrete. The use of recycled fibers from industrial or postconsumer waste offers additional advantages of waste ...

Abstract: Experiments to study the yield surface of 304 stainless steel with either 20 percent tension or 20 percent shear prestrain have been conducted. Explicit transformation equations have also been ...
