Draft CWAs on a test method and guidelines on advanced high strength steel sheets


The main objective of the CEN/WS 'Fracture toughness evaluation methodologies applied to advanced high strength steel sheets' is to provide guidelines describing different methodologies, informing about their suitability, and to provide recommendations that can be applied by the manufacturers during the planning, design, and operational phases of the manufacture of AHSS sheets.

The CEN/WS is developing two draft CWAs:

  • CWA “Test method for the determination of a cracking resistance index for advanced high strength steel sheets”, which describes a single-specimen testing procedure for the evaluation of a cracking resistance index (CRI) for AHSS sheets with thicknesses between 0,5 mm and 3,0 mm;
  • CWA “Guidelines for the evaluation of the plane stress fracture toughness of advanced high strength steel sheets in the frame of fracture mechanics”, which provides information of interest about the fracture toughness evaluation of thin high strength metal sheets and its implication on sheet metal formability and crashworthiness.

All interested parties are invited to submit comments on the two CWAs using the commenting form below, to the Workshop secretary, Mr. Javier Lopez-Quiles Pastor (jlopezquiles@une.org). Deadline: 18 June 2023
