Micro-cracks detection in Photo-Voltaic Cells by Infrared Thermography [PDF]

, 2004
In this paper, a technique is presented to detect micro-cracks on photo-voltaic cells by infrared thermography. The originality of the system comes from the thermoelectric stimulation used to generate thermal transients at micro-crack locations.

Three-dimensional boundary element and experimental analysis of lubricant ceramic surface ring cracks in rolling contact.

Surface defects such as ring cracks are located on silicon nitride ceramic rolling elements.The random nature of ring crack position creates difficulties in predicting rolling contact fatigue (RCF) life.

A micromechanical model on specific damping capacity caused by micro cracks [PDF]

, 2015
Dispersed micro cracks are widely found in engineer materials, e.g. concrete, ceramic and composite. Specific damping capacity (SDC) caused by friction on micro crack surfaces (FSDC) was investigated in this study. Firstly, frictional energy dissipation (
