MULTISCALE MODELING FOR THE SCIENCE AND ENGINEERING OF MATERIALS

Abstract

Material discovery and development drives innovation and is a key component for almost all cutting edge technologies today. With progress in compute power and numerical methods, multiscale modeling has been a rapid growing requirement in the science and engineering of materials. However, unresolved challenges in true multiscale modeling have thus far prevented engineers and scientists from realizing its full potential and as a result, its success in production applications is not widespread. Particularly difficult challenges to multiscale simulations are the vastly different physics at different scales among different materials manufactured with different procedures and used in different applications with different performance indicators. To help address these challenges Dassault Systèmes has brought together the power of multiple software brands to combine the expertise in multi-physics simulations from quantum, molecular to continuum and system scale with a purpose to promote the production usage of multiscale modeling to design, develop and validate sustainable and programmable materials. In this paper, the key multiscale modeling and simulation technologies from Dassault Systèmes will be introduced with a focus on the realistic industrial applications via an end-to-end digital thread on the 3DEXPERIENCE platform. Our goal is to provide a fundamental and general framework to allow engineers to construct micro-scale models, deduce the macro-scale laws and the constitutive relations by proper homogenization, with seamless integration to our native material modeling capabilities, for quantitative, rigorous analysis of the overall response and failure modes of adva
