On the need for material model databases: A state-of-the-art review

Abstract

The majority of FEA simulation software offers a library of material properties. However, the included materials are generic or the most common and do not represent the entire materials market. The problem is fairly solved by the material suppliers that usually provide the material properties of their products or by data available in materials databases. However, the information provided by the materials databases does not include experimental data nor provide information on the testing procedures. Due to this absence, users can not verify the information or its accuracy on the material database. Moreover, data related to material constitutive models, required for accurate simulations seems to be absent. This study focuses on the materials databases available as open-source or paid services, demonstrating that existing macroscopic materials databases do not have information on the experiments conducted nor have constitutive behavior characterization models.
