Abstract: The paper describes a new finite element, derived from the classical constant strain element, in the context of localization analysis of elastic-plastic materials. The formulation is based on the “enhanced strain” concept, ...

Abstract: Using the fully implicit rule for temporal integration, one may define a class of simple plasticity models, for which an incremental potential energy can be constructed. This potential has, in general, multiple stationary ...

Abstract: A plastic ball grid array component interconnect has been experimentally investigated and modeled on the basis of micropolar theory. The experimental results were analyzed, and the data also ...

Abstract: Characteristics of finite element solutions involving strain‐softening plasticity are discussed with reference to strain localization and stability for simple uniaxial problems. The stability of localized and nonlocalized ...
