Abstract Scope |
The importance of accurate material properties information for engineering calculations and simulations can never be overstated. Conventional mechanical properties such as yield strength, tensile strength, and hardness can vary more than tenfold for structural steels at room temperature due to variations in alloying elements, heat treatment and fabrication.
While large material databases and material selection software can help with these challenges, it is technically impossible to have all properties readily available from each type of experiment and standard. However, recent developments in artificial intelligence and machine learning provide an opportunity to overcome this gap.
This paper presents a machine learning tool able to predict material properties at a wide range of diversified materials, such as stainless steels, aluminum, refractory alloys and polymers at various temperatures, heat treatments and delivery conditions. In most cases, the accuracy achieved in terms of relative error is above 90% and frequently above 95%. |
