Data for: Notch effect on the fracture of a polymeric film

This dataset contains the results of performing the plane stress fracture toughness of a bio-based copolyester using double edge notched tension specimens. Specifically, the load-displacement and the ligament length-displacement curves are presented. From these curves, the EWF, the J-integral, and the crack tip opening displacement approaches have been applied in a unique set of specimens. The influence of the notch quality on the fracture parameters has been also studied by using two different notch sharpening procedures, the femtosecond laser ablation, and the razor blade sliding.
