Damage characterization and damage percolation modelling in aluminum alloy sheet

Acta Materialia, 2001
Abstract Tessellation methods have been applied to characterize second-phase particle fields and the degree of clustering present in AA5754 and AA5182 automotive sheet alloys. A model of damage development within these materials has been developed using a damage percolation approach based on measured particle distributions.

Characterization of Damaged Skin by Impedance Spectroscopy: Chemical Damage by Dimethyl Sulfoxide

Pharmaceutical Research, 2013
To relate changes in the electrochemical impedance spectra to the progression and mechanism of skin damage arising from exposure to dimethyl sulfoxide (DMSO).Electrochemical impedance spectra measured before and after human cadaver skin was treated with neat DMSO or phosphate buffered saline (control) for 1 h or less were compared with electrical ...

Smoke Characterization and Damage Potentials

2016
Smoke is a mixture of (1) particulates consisting of soot, semi-volatile organic compounds (SVOC), and solid inorganic compounds; and (2) non-particulates consisting of very volatile organic compounds, volatile organic compounds, and liquid and gaseous inorganic compounds.

Horizontal Well Damage Characterization and Removal

SPE Production & Facilities, 1993
Summary This paper presents conceptual and mathematical descriptions of the damage along and normal to a horizontal well. Expressions for the skin effect that take permeability anisotropy into account are developed. Stimulation methodology, respecting the shape of damage, is presented.

Damage characterization using reverberant decays

Ultrasonics, 1998
A new, quantitative, non-destructive evaluation technique is described for estimating both the severity and spatial extent of damage in engineering materials. The technique exploits the unique decay character of non-proportionally damped systems. Theoretical expressions relating decay and damage characteristics are presented and compared with physical ...

Damage characterization and fatigue modeling of CFRP subjected to cyclic loading

Composite structures, 2018
Fatigue damage evolution in CFRP is characterized by variation of local transverse strain from digital image correlation (un-notched) and temperature variation from infrared thermography (notched). The damage evolves over 2–3 stages.
