ADACS, Inc. (Advanced Durability Assessment and Consulting Services) develops and markets advanced fatigue software tools (TFAT) and methodologies for the endurance assessment of engineering components, systems, and structures. An emphasis is placed on research and development in the area of Thermo-Mechanical Fatigue (TMF). In addition, the company provides on-site and off-site consulting and development services to design and manufacturing customers. TFAT (Thermomechanical Fatigue Analysis Tools) is a commercial software for the computation of thermomechanical fatigue lives of components experiencing thermal and mechanical loading conditions. TFAT allows Ansys customers to assess the TMF life of their components by reading the results of nonlinear transient FEA analysis directly out of the Ansys .rst database. It can import standard output variables as well as Solution Dependent Variables (SVAR’s) from Usermat. TFAT also contains modules that allow for the material determination of rate-dependent constitutive model for high temperature application such as the Chaboche model in combination with the Perzyna or EVH models.
