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 ...

Abstract: This paper is devoted to the experimental study of chemical degradation effects on the mechanical behavior of sandstone. The sandstone samples were immersed in acid solutions with different pH values to undergo chemical ...

Abstract: This paper is devoted to coupled hydromechanical modeling of an underground cavity subjected to excavation, drying, and resaturation. An elastoplastic damage model is proposed for the description of poromechanical behavior ...

Abstract: A new anisotropic damage model is proposed to describe the mechanical and poromechanical behavior of brittle rocks in drained and undrained conditions. Although phenomenological, the model is based on physical grounds of ...

Abstract: This paper deals with experimental investigation and numerical modeling of drying effects on the mechanical behavior of cement-based materials. First, the main results from an experimental study on the mechanical behavior ...
