Experimental and numerical study of laser induced spallation in glass

摘要: The study of dynamic failure under shock loading in very brittle materials such as glass is usually limited by the severe destruction tested specimens. In this article, an original approach toward studying phenomenon, based on post‐shock examination damaged targets, presented. A high‐power pulsed laser has been used to generate short compressive pulses and produced damage samples. Spallation shown result formation a fractured layer near rear free surface influences main experimental parameters upon finite thickness have determined. data obtained work out simple macroscopic description spallation glass, then coupled constitutive model implemented one‐dimensional simulation code. resulting able predict extent induced soda‐lime target by...
