Statistical microdamage mechanics and damage field evolution [PDF]

open access: yes, 2001
Discussed are the underlying background of statistical microdamage mechanics, the fundamental partial differential equation of evolution of microdamage number density, two basic solutions, and the saturation of microdamage number density evolution ...

Damage mechanics and fatigue life assessment of composite materials [PDF]

open access: yes, 1999
The present state of fatigue life assessment of composite materials is largely empirical. This paper discusses how the discipline of damage mechanics can elevate this status to a mechanisms-based methodology.

Oriented damage in ductile sheets: Constitutive modeling and numerical integration [PDF]

open access: yes, 2007
Thermodynamics with internal variables provides a framework for constitutive modeling of elasto-plastic deformations. Within the scope of the theory, constitutive and evolution equations for ductile, elasto-plastic materials with mixed (isotropic and ...

Damage evaluation and damage localization of rock [PDF]

open access: yes, 2004
Knowledge of damage accumulation and corresponding failure evolution are prerequisite for effective maintenance of civil engineering so as to avoid disaster. Based on statistical mesoscopic damage mechanics, it was revealed that there are three stages in

Research Review on the Damage Theoretical Model of Metal Materials

open access: yesTaiyuan Ligong Daxue xuebao, 2023
The plastic deformation of metal material is accompanied by surface defects, internal defects, damage cracks, etc., and these defects seriously restrict the processing of metal and its performance improvement.

Modelling of dynamic damage and failure in aluminium alloys [PDF]

open access: yes, 2012
A physically based damage and failure model, applicable to orthotropic metals is proposed in this paper. To account for the physical mechanisms of failure, the concept of thermally activated damage initially proposed by Klepaczko [1], has been adopted as

Uncertainty quantification in damage mechanics models [PDF]

open access: yes, 2023
Plechac, PetrComputational modeling of material response, at the macroscopic scale, under external stimuli, is paramount to predicting material failure in various structural applications.

Mechanisms of ischemic brain damage [PDF]

open access: yesNeuropharmacology, 2008
In the United States stroke is the third leading cause of death and the leading cause of disability. Brain injury following stroke results from the complex interplay of multiple pathways including excitotoxicity, acidotoxicity, ionic imbalance, peri-infarct depolarization, oxidative and nitrative stress, inflammation and apoptosis.

A Review on Damage and Rupture Modelling for Soft Tissues

open access: yesBioengineering, 2022
Computational modelling of damage and rupture of non-connective and connective soft tissues due to pathological and supra-physiological mechanisms is vital in the fundamental understanding of failures.
