TTV - Thickness Toughness Validator

TTV (Thickness Toughness Validator) is a software tool developed and maintained by ArcelorMittal Steligence® Engineering. The first version was released in July 2023 and is free to download. It is a simple, intuitive, and quick tool for validating steel construction details according to the recommendations and requirements contained in the EN 1993-1-10 standard. The simplified method (EN 1993-1-10, Clause 2.3) has been implemented in the program. The advanced method (EN 1993-1-10, Clause 2.4) based on more advanced fracture mechanics methods has also been implemented for specific details. Both the software and the user guide are provided in the downloadable folder.
