Quasi-brittle materials exhibit significant heterogeneity due to their complex mesoscopic
components and microdefects, and their macroscopic mechanical behavior depends …

The use of manufactured sand as fine aggregate in concrete has been widely adopted in
engineering to alleviate the shortage of natural river sand supply. However, there are many …

Fiber reinforced concrete (FRC) has gained increasing interest in recent years due to its
superior mechanical properties compared to plain concrete. The failure of it is a process in …

In this paper, we shall present a new micromechanical damage model for capturing the
mechanical behaviors of quasi-brittle geomaterials under a wide range of compressive …

In this study, a microdamage model by introducing the damage of crystal is proposed.
Damage variables are defined for each slip system, and the damage-coupled crystal …

A multiscale mechanical model is proposed to quantitatively describe the macro-mechanical
behavior of fiber reinforced concrete (FRC) based on its multiscale material compositions …

该文的目的是建立一种新的, 相对简单的混凝土各向异性塑性损伤本构模型,
以方便的模拟混凝土结构的破坏行为. 为了更好地描述混凝土在拉, 压荷载作用下的不同损伤 …

The mechanism of frictional contact is investigated between a blunt tool and quasi-brittle
rocks with anisotropic damage. A recently developed anisotropic elasto-plastic-damage …

The aim of this paper is to numerically investigate the relationship between mechanical
strength and microstructural evolution of concrete, firstly, based on the geometrical …

In this study bond-based peridynamic formulation is developed and coupled with the finite
element method (FEM) to simulate crack growth in orthotropic materials. The coupled PD …
