Production of Cracks in ZnS under a Uniform Dynamic Stress Field.
Abstract
Plate impact and exploding cylinder experiments were performed on CVD ZnS and PMMA, respectively, to establish the applicability of the methods for studying dynamic fracture of brittle materials. Prerequisites for successful plate impact experiments are precise velocity control in the tens-of-meters per second range and specimen encapsulation. Prerequisites for successful exploding cylinder experiments are large specimens (to contain cracks), external compressive hoop stresses, and control over the type and amount of explosive. With these prerequisities, both methods appear to be useful for studying fracture response in fragile materials. (Author)
