Modelling of Damage in Blanking Processes
Key Engineering Materials, 2013Fracturing by ductile damage occurs quite naturally in metal forming process due to the development of microcracks associated with large straining or due to plastic instabilities associated with material behavior and boundary conditions. Metal forming processes generally introduce a certain amount of damage in the material being formed.

Chemical models and radiation damage
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1985Abstract E.s.r. spectroscopy has been used in conjunction with an aqueous flow system to investigate both the metal-catalysed decomposition of hydrogen peroxide to OH* and the subsequent reactions of this radical with a variety of biomolecules. Particular emphasis is placed on the effects of pH and ligand on the FeII—H2O2 reaction and

A rate-dependent dynamic damage model in peridynamics for concrete under impact loading
, 2020To study the dynamic behavior and impact damage and failure of concrete materials and structures, a dynamic damage model was reformulated under the framework of the non-local peridynamic theory in this paper.

On Nonstationary Cumulative Damage Models
Journal of Applied Mechanics, 1982In this paper, we continue our study of embedded Markoff Chain Models of Cumulative Damage. We introduce and discuss a time transformation that leads to a condensation method. This method appears to be unusally comprehensive and a practical way to study nonstationary models of cummulative damage.

An improved nonlinear damage model of rocks considering initial damage and damage evolution
, 2020The experimental results show that the creep properties of the rocks are affected by the initial damage, and the damage evolution also has a significant impact on the time-dependent properties of the rocks during the creep.

An improved nonlinear cumulative damage model for strength degradation considering loading sequence
, 2020In order to determine the effect of different loads on fatigue damage, a strength degradation model is proposed according to the law of residual strength degradation of metal materials.

Fatigue damage model of concrete materials
, 2020Based on the continuum damage mechanics theory of concrete materials under fatigue loading; a phenomenological fatigue damage model due to nuclei-propagation of microdefects, microvoids and fractal of rendered concrete in conjunction with more compliant ...

A Probability Model of Radiation Damage
Nature, 1952IN developing the mathematical theory of radiobiological phenomena it is necessary to consider two separate, yet related, problems. The first problem is concerned with the probability of occurrence of effective ionizing radiations within a so-called sensitive volume (or mass) of a living organism.
