ToughSteel Event

Webinar - Application of fracture toughness to assess crashworthiness

This is the fourth out of five training webinars organized in the ToughSteel project. ToughSteel aims in spreading the usage of fracture toughness to assess crack-related problems in sheet metals to the European industry. Coordinated by Eurecat Technology Center, ToughSteel involves and engages the main actors of the sheet metal forming community with the objective to promote, disseminate and transfer the know-how acquired about the use of fracture toughness as a tool to address cracking problems in forming and in-service performance of AHSS. 

In this specific training webinar, you will learn how fracture toughness concepts are used to assess the crashworthiness of automotive components.
