For this 9th International Conference in the series organised by the European Structural Integrity Society - Technical Committee 4 on Fracture Mechanics related to Polymers, Polymer Composites and Adhesives. Papers relating to fracture mechanics testing methods, theoretical and numerical developments and applications of fracture mechanics to industrial applications are all welcome. Of special interest are novel polymer-based materials and composites, e.g., renewable or biodegradable and polymer-based materials made with new technologies, e.g., additive manufacturing.
