Abstract

Stretch blow moulding process has been applied to manufacture of bioresorbable vascular scaffold (BVS) made by poly (l-lactic acid) (PLLA) improve the mechanical properties of product. Biaxial stretching test was conducted to obtain the mechanical properties of amorphous PLLA materials at temperatures above glass transition. The glass-rubber (GR) constitutive model was adopted to model the mechanical behaviour and can be used for the simulation for the forming process
