A novel specimen design to establish the forming limit diagram (FLD) for GFRP through stamping test

Composites Part A: Applied Science and Manufacturing, 2020
Abstract Inspired by metal forming tests, the conventional forming limit diagram (FLD) was employed to characterize the forming properties of the Glass Fiber Reinforced Polypropylene (GFRP) composite in this study. The strain history of GFRP specimens was captured by using a 3D digital image correlation (DIC) system.
