摘要
Holographic interferometry is used to determine the fracture process zone of mortar and concrete. The tests reveal the presence of a significant fracture process zone prior to peak load of the specimen. The fracture process zone can be subdivided into an elliptical, continuous region and a narrow but long, disrupted band along which load is transferred due to aggregate interlock. The larger the aggregates, the more pronounced is this fracture process zone. © 1990.
