..., and then sliced and notched using a laboratory saw. The notch acts to facilitate crack initiation. Notched samples are subjected to a strain controlled compressive load in three point bending. Crack opening displacements (CODs) and loads are recorded in real time using four linear variable displacement...

... with a ratio of minimum load to maximum load R of 0.1. The incidence of crack closure was examined during fatigue with both direct current potential drop and crack-opening-displacement (COD) methods; COD was found to be more reliable for closure measurement than potential drop. In contract to the fine-grained...
