...Kaifeng Zeng; Zhen-Yu Yin; Huabei Liu; Yin-Fu Jin The effect of particle breakage associated with the mechanical behaviour of coral sand has been widely investigated, but not under a three-dimensional stress state with different stress paths and loading directions. In this study, a series of true...

.... The hyperelastic description of the material is then conjugated with a state-dependent bounding surface plasticity model to capture the soil response in a hyperelastic–plastic framework. The influence of particle breakage on the stress–strain response of soils is incorporated by adjusting the critical state void...

...-induced densification but overlook breakage-induced degradation. Particle breakage disrupts inter-particle interlocking and creates finer debris, promoting volumetric contraction and weakening material stiffness. This study introduces a novel cyclic constitutive model for predicting plastic strain...

... reduces particle breakage. This study also describes a numerical analysis following a coupled discrete–continuum modelling approach to examine the complex interaction of discrete ballast grains with the recycled rubber mat. In particular, a mathematical framework coupling the discrete and continuum...

...Mengmeng Wu; Jianfeng Wang In this paper, a novel investigation of the particle breakage behaviour of sands is made using combined techniques of X-ray micro-computed tomography (μCT) and sand particle tracking. First, an in situ μCT triaxial test on a miniature sand specimen is conducted to allow...

... state under high confining pressure. Under the drained condition, specimens constantly contracted and exhibited significant particle breakage. During the isotropic compression, the growth rate of plastic volumetric strain of coral sand visibly decreased as the confining pressure increased. Furthermore...

...Chaomin Shen; Sihong Liu; Liujiang Wang An elasto-plastic constitutive model for rockfill materials considering particle breakage is proposed. Although numerous constitutive models have been proposed for rockfill materials, most of them are mainly based on empirical results, without consideration...

...Tzou-Shin Ueng; Tse-Jen Chen The effect of particle breakage on the shear strength of sand is studied by considering the energy consumption due to particle breakage at the contacts between sand particles. A stress–dilatancy relationship for sand under a triaxial loading condition is developed...
