From Brittle to Ductile Fracture in Disordered Materials [PDF]
, 2010 We introduce a lattice model able to describe damage and yielding in heterogeneous materials ranging from brittle to ductile ones. Ductile fracture surfaces, obtained when the system breaks once the strain is completely localized, are shown to correspond

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 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 ...

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

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.

Rain erosion damage in brittle materials
Engineering Fracture Mechanics, 1983 Abstract In order to understand the processes involved in the high-velocity rain erosion of brittle materials the impact damage produced in soda-lime-silica glass by single and multiple jet impact was studied. The damage was quantified by measuring the post-impact strength of specimens.

Dehydration drives damage in the freezing of brittle hydrogels [PDF]
Science AdvancesIt is widely known that freezing breaks soft, wet materials. However, the mechanism underlying this damage is still not clear. To understand this process, we freeze model, brittle hydrogel samples, while observing the growth of ice-filled cracks that ...

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 ...
