Light Damage as a Model of Retinal Degeneration
2012The induction of retinal degeneration by light exposure is widely used to study mechanisms of cell death. The advantage of such light-induced lesions over genetically determined degenerations is that light exposures can be manipulated according to the needs of the experimenter. Bright white light exposure can induce a synchronized burst of apoptosis in

A nonlinear creep damage model for salt rock
International journal of damage mechanics, 2018In the creep tests, stress is no longer a constant and increases gradually under the influence of damage occurring during accelerating creep, which is a slow-loading process rather than a conventional creep. With the accumulation of the damage over time,

Composite structures, 2018
Low velocity impact (LVI) has always been a potential threaten to composite structures. This out-of-plane dynamic impact load easily leads to a dramatic increase of the strain state in the material transverse plane, which can affect the dynamic stress ...

Modelization of damage by abrasion
Wear, 1993Abstract This paper takes steps to determine the non-negligible parameters governing the wear process. Modelization leads to the generalization of the Archard law. A new non-dimensional law is proposed in which the sharpness of the abrasive, its mineralogical hardness and the microstructural characteristics (elasto-plasticity and toughness) of the ...

Strength of Materials, 1990
The theoretical defect size distribution has been derived on the basis of the kinetic formation and growth parameters. Formulas are derived for the mathematical expectation and variance for the damage in a uniformly strained material. The damage nonuniformity occurring with a Poisson distribution for the defect size in the bulk can have a substantial ...

It has already been pointed out in the previous chapters that the performance degradation of MOSFET devices due to hot-carrier effects leads to the degradation of circuit performance over time. The extent of the hot-carrier damage each transistor experiences is determined by its terminal voltage waveforms, i.e., by the operating conditions of the ...

Abstract Because the skin is always in contact with oxygen and occasionally exposed to UV light, different kinds of photobiological cutaneous reactions inevitably occur resulting in photo-oxidative stress. Acute actinic damage, e.g.
