Micromechanisms of dynamic fracture in biopolyester
A biopolymer is a naturally occurring polymeric substance formed from individual molecules in a biological system. Biopolymers can also be synthetic by manipulation of the individual molecules once obtained outside the biological system. In the present investigation, attempts are made to investigate the basic mechanisms of dynamic fracture in a polyester biopolymer. Izod impact tests of polyester ...
