Damage Losses Assessment Models

2016
The chapter focuses on the definition of a loss function which has been one of the first indicators used to determine resilience. Different models to evaluate the damage losses are provided, approaching the problem in probabilistic terms using fragility functions and analyzing the different type of uncertainties which appear in the resilience ...

Turbulence in Blood Damage Modeling

The International Journal of Artificial Organs, 2016
Purpose To account for the impact of turbulence in blood damage modeling, a novel approach based on the generation of instantaneous flow fields from RANS simulations is proposed. Methods Turbulent flow in a bileaflet mechanical heart valve was simulated using RANS-based (SST k-ω) flow solver using FLUENT 14.5. The calculated Reynolds shear stress (RSS)

Damage process modeling on SMC

Journal of Applied Polymer Science, 1996
The damage processes taking place in SMC, which has been subjected to monotonically increasing tensile loads, are analyzed and the stress-strain curves are calculated. SMC is viewed as a laminate consisting of fiber bundles embedded in a resin/filler matrix.

Chemical models and radiation damage

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1985
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 Fe II —H

On Nonstationary Cumulative Damage Models

Journal of Applied Mechanics, 1982
In 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.

UV damage models

2000
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.

Nonlocal Elastic-Damage Models

2014
A theory of nonlocal isotropic damage for elastic quasi-brittle materials is presented under the assumption of isothermal conditions and small deformations. Key ingredients of this theory are a self-adjoint (regularization) operator which transforms a local field into a related nonlocal one while preserves uniform fields and a free energy which depends

A stochastic damage model

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 ...

Modeling explosive cellular damage

SPIE Proceedings, 2008
We derive a closed-form expression for the cell radius change induced by preferential absorption of continuous wave non-ionizing radiation. The result is an approximate solution to a nonlinear ordinary differential equation. The approximation is shown to be reasonable by numerical comparison.© (2008) COPYRIGHT SPIE--The International Society for ...
