With advanced high-strength steels (AHSS), standard formability tests yield insufficient data to determine the failure strain that triggers edge cracking. EWI has successfully evaluated a new testing method on DP780 steel which has the potential to help the automotive industry reduce design time, scrap rates, and other costs. New Method for Determining Failure Criteria for...

Continuous fiber reinforced thermoplastic composites (CFRTPCs) are increasingly being used in aerospace, automotive, and oil & gas (O&G) due to their low cost, recyclability, complex shape adaptability, high strength, and low weight. The CFRTPC market worldwide is projected to grow by US$634.1 million, driven by a compounded growth of 8.3%. Continuous Carbon Fiber displays the potential...

When it comes to predicting sheet metal failure during forming, the standard tool has been the forming limit diagram (FLD). With advance materials like AHSS, aluminum, and magnesium alloys that are now being used more frequently in automotive, aerospace, and heavy equipment manufacturing, the FLD does not model failure accurately. A newer method, Generalized Incremental...
