Abstract: In this paper an attempt is made to provide a macroscopic description of undrained deformation, in saturated granular materials, in the presence of a shear band. First, the case when both constituents (i.e., the intact and ...

Abstract: The focus of this paper is on the description of progressive fracture in distal radius in the event of a fall onto an outstretched hand. The inception of fracture, which involves formation ...

Abstract: This paper deals with the dynamic analysis of foundations in saturated soils. In the first part, a mathematical formulation is briefly outlined in which soil is considered as a two-phase medium comprising the soil skeleton ...

Abstract: In this paper a constitutive relation is developed for concrete reinforced with two orthogonal sets of steel bars. The formulation incorporates a homogeneous deformation mode, prior to cracking, as well as a localized mode ...

Abstract: In this paper, a nonlinear continuum theory is applied to model the thermomechanical behavior of concrete subjected to alkali-silica reaction. The reaction results in formation of silica gel around the aggregate particles, ...

Abstract: The paper presents a macroscopic failure criterion for structural masonry. This criterion is derived within the framework of the critical plane approach. First, a general discussion is provided examining the performance ...

Abstract: In this paper a constitutive relation is developed for reinforced concrete subjected to a continuing alkali-silica reaction. The chemo-mechanical interaction is described within the framework of chemo-plasticity. The ...

Abstract: This paper is concerned with a mathematical description of the undrained response of partially saturated soils having a continuous liquid phase (water) and a gas in the form of discrete bubbles. Two types of soil structures ...

Abstract: The primary objective of this study was to demonstrate that a significant degree of anisotropy may occur in particulate materials that have nearly spherical aggregates (i.e., are typically considered as isotropic) provided ...

Abstract: This paper presents a mathematical framework for modeling the creep phenomenon in frictional materials exhibiting a strong inherent anisotropy. The instantaneous time-independent response is described by invoking a plasticity ...
