This paper describes recent developments in a large database of advanced material properties for metallic materials, polymers, ceramics, composites, and other non-metallic materials. This database, called Extended Range, relies on a proprietary methodology that combines property acquisition and assessment, and it is now integrated into the new Total Materia database in order to provide the global engineering community with mechanical and physical properties needed for advanced CAE (Computer Aided Engineering) and FEA (Finite Element Analysis) calculations and simulations.
A special focus of Extended Range are advanced material properties needed for nonlinear calculations regarding plasticity, fatigue, crack growth, time-related deformation etc. Information on these advanced properties is very hard to find and this evident lack of knowledge about material properties poses one of the highest risks in structural design, accounting for over 29% of structural failures.
In Extended Range, advanced material properties have been divided to (1) stress-strain curves, (2) formability, (3) cyclic properties, (4) fracture mechanics, and (5) creep properties. The biggest challenge in providing these properties for a large number of engineering materials and service conditions is a general scarceness of experimental data. Besides collecting and consolidating information for more than 16,000 materials and 130,000 datasets from more than 1,400 references, with the number growing through monthly upgrades, a specific set of algorithms has been developed for assessing and interpolating properties under various conditions (service temperature, heat treatment etc.), thus further providing property estimates for over 60,000 materials.
The paper will provide an insight into newly developed algorithms and functionalities, such as formability diagrams, anisotropic data and r-factors, stress-strain curves comparison and interpolation for various strain rates, statistical approach to cyclic properties and property assessment based on material comparison. Also, new, extended property data export functionalities and integration possibilities with CAE tools will be presented.
