Damage Spreading in the Ising Model

, 1997
We present two new results regarding damage spreading in ferromagnetic Ising models. First, we show that a damage spreading transition can occur in an Ising chain that evolves in contact with a thermal reservoir.

Coupled plastic-damaged model [PDF]

Computer Methods in Applied Mechanics and Engineering, 1996
A constitutive model that couples plasticity and damage is presented. The model is thermodynamically consistent and comes from a generalization of classical plasticity theory and isotropic damage theory of Kachanov. Coupling between plasticity and damage is achieved through a simultaneous solution of the plastic and the damage problem.

Progressive Damage Modelling [PDF]

, 2008
The application of bonded joints is increasing due to their several advantages to alternative bonding methods. As a result, more efficient predictive tools are necessary to increase the confidence of designers. In this context, cohesive and continuum damage models acquire special relevancy owing to their capacity to simulate damage onset and growth ...

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 ...

Damage test and model study of soft and hard interbedded rock based on piezoelectric ceramics and DIC

Meikuang Anquan, 2023
In order to explore the damage evolution law of soft and hard interbedded rock after failure, three groups of rock-like test blocks (soft rock, interbedded rock and hard rock) were made by using the similar model theory.
