The Use of Machine-Learning Techniques in Material Constitutive Modelling for Metal Forming Processes

Abstract: Accurate numerical simulations require constitutive models capable of providing precise material data. Several calibration methodologies have been developed to improve the accuracy of constitutive models. Nevertheless, a model’s performance is always constrained by its mathematical formulation. Machine learning (ML) techniques, such as artificial neural networks (ANNs), have the potential to overcome these limitations. Nevertheless, the use of ML for material constitutive modelling is very recent and not fully… Show more

“…The accuracy of the numerical simulations requires constitutive models capable of describing the mechanical behavior of the material. On this topic, two papers of the special issue [3,4] investigated the application of ML to constitutive modeling and material parameters identification. Lourenço et al [3], explored and discussed the potential contributions of ML in terms of elastoplasticity constitutive modelling.…”

“…Over the past decade, the progress of ML has greatly impacted the entire spectrum of physical sciences, including materials science 6 and a reflection of that is the creation of the material genome initiative 7 as a path for accelerating materials development and rationally designing materials through the use of data-driven methods. Other works report the use of ML linear regression methods to build force constant models for thermodynamic properties of materials used in physics and chemistry 8 and the data-centric approach was used for polymer crystals 9 , pharmaceutical science 10 and material constitutive modeling for metal forming processes 11 , with likely many more important developments to come shortly. Also, the importance of the increasing quantity of data recently collected (from experiments and simulations), for the advancement of the ML as a tool for phosphor design has already been discussed 12 .…”

“…As a result, there is a rising demand for real-time, data-driven approaches to quality control that can swiftly identify and rectify issues. The incorporation of machine learning models, central to the Industry 4.0 era, offers a powerful approach to achieving the demand [4][5][6][7][8]. These models can analyse real-time data to predict potential defects and enable immediate corrective actions, thereby elevating the efficiency and accuracy of quality control processes [9].…”
