Abstract

Three tests using photometrical analysis were completed for crack closure estimation and covered at present paper. Constant and variable amplitude loading cases are both analyzed. Inadequacy of contemporary crack closure estimation models to explain results of the simple tests is shown. Hysteresis loops are given occurring due to various material reactions on tension and compression and specifying displacement of material close to crack tip.

Keywords: Photometrical analysis, energetical approach, crack closure, hysteresis loop, variable amplitude loading
