TTV (Thickness Toughness Validator) is a tool developed internally by ArcelorMittal Steligence® Engineering. It is a simple tool for validating the selection of toughness subgrades according to the recommendations and requirements of the EN 1993-1-10 standard. This standard provides design guidance for the selection of steel for fracture toughness, imposing maximum detail thicknesses depending on material, temperature, and load level.
The simplified method (EN 1993-1-10, Clause 2.3) is based on a simple table check. As it is general, it is based on safe assumptions that may not always correspond to specific project specifications.
The advanced method (EN 1993-1-10, Clause 2.4), based on more advanced fracture mechanics methods, has therefore been implemented in order to perform a more specific check to deliver more advanced results.
This tool is entirely based on Eurocode background methods and their application. As such, the advanced method will deliver the same results as the tables of the simplified method if the same assumptions are introduced. The user guide and validation examples are provided in the tool’s download folder.
