Osaka, Japan, September 02-06, 2013.In this paper we analyze, using the Finite Element Method, the process of brittle-ductile transition in the failure mode observed in polycarbonate notched specimens under impact loads. In order to analyze this transition we have implemented, through a user subroutine, a damage model which combines a tensional fracture criterion and an energetic, acting simultaneously. The competition between both criteria predicts the difference in material behavior from a critical impact velocity, and how this transition is produced on different planes through the thickness of the specimen. These results show the necessity of employing three-dimensional models for its study.6application/pdfeng© 2014 Trans Tech PublicationsPolymersDamage ModelsFailure-Mode Transitionconference paperIngeniería IndustrialIngeniería Mecánica10.4028/www.scientific.net/AMM.566.310open access310315Proceedings of the 8th International Symposium on Impact Engineering566CC/0000021911
