An alternative 3D model for damage induced anisotropy and unilateral effect in microcracked materials [PDF]
, 2003 A three-dimensional model of damage by microcrack growth is proposed to account for the mechanical behavior of quasi brittle materials (especially for concrete and rocks). The emphasis is put on the induced anisotropy and on the elastic moduli dependence

Description of Brittle Damage in Concrete
Communications, 2002 A simple model of the brittle damage evolution in concrete is presented. The damage evolution is assumed as an isotropic one and the level of damages in material is described by the scalar parameter. The physical equations for this case are formulated.

A brittle star-like robot capable of immediately adapting to unexpected physical damage [PDF]
Royal Society Open Science, 2017 A major challenge in robotic design is enabling robots to immediately adapt to unexpected physical damage. However, conventional robots require considerable time (more than several tens of seconds) for adaptation because the process entails high ...

Damage-cluster distributions and size effect on strength in compressive failure [PDF]
, 2012 We investigate compressive failure of heterogeneous materials on the basis of a continuous progressive damage model. The model explicitely accounts for tensile and shear local damage and reproduces the main features of compressive failure of brittle ...

A peridynamic model for brittle damage and fracture in porous materials
International Journal of Rock Mechanics And Mining Sciences, 2019 We introduce a peridynamic (PD) model for simulating brittle damage and fracture in elastic porous materials based on an Intermediate Homogenization (IH) approach.

Understanding fast macroscale fracture from microcrack post mortem patterns [PDF]
, 2011 Dynamic crack propagation drives catastrophic solid failures. In many amorphous brittle materials, sufficiently fast crack growth involves small-scale, high-frequency microcracking damage localized near the crack tip.

An analytical model to predict the depth of sub-surface damage for grinding of brittle materials
CIRP - Journal of Manufacturing Science and Technology, 2021 This paper proposes an analytical model for predicting grinding-induced sub-surface damage depth in a silicon wafer. The model integrates the dislocation kinetics for crack initiation and fracture mechanics for crack propagation for the first time ...

Study of Damage Constitutive Model of Brittle Rocks considering Stress Dropping Characteristics
Advances in Civil Engineering, 2020 Deep brittle rock exhibits characteristics of rapid stress dropping rate and large stress dropping degree after peak failure. To simulate the whole process of deformation and failure of the deep brittle rock under load, the Lemaitre strain equivalent ...
