The effects of specimen thickness, stress ratio (R) and maximum stress intensity factor (Kin.x) on crack closure (or opening) were studied using a 2219-T851 aluminum alloy. The crack length and the occurrence of crack closure were measured by an electrical potential method. The experimental work was
