    Research output: Contribution to journalArticlepeer-review


    Dynamic fracture of PMMA was studied using a Cranz-Schardin high-speed camera. The single-edge-notched specimen was pin-loaded with special fixtures so that it could split and fly away after the fracture. The flying velocity was measured to estimate the elastic energy stored in the specimen. The nonelastic energy was also estimated from the visco-plastic deformation. The fracture energy was evaluated and correlated with the external work applied to the specimen.
