The main objective of this document is to provide an industrial user guideline to describe methodologies of fracture toughness evaluation in sheet metals. The user guideline compiles relevant findings from research developed in previous and ongoing RFCS projects and academic research.

Moreover, it includes recommendations to be applied during the planning, design, and operational phases of the manufacture of AHSS sheets and components, as well as successful industrial case studies. The user guideline will contribute to a more efficient fracture resistance and crashworthinessprediction in different industrial applications.
