Abstract

How would you……describe the overall significance of this paper? This paper provides an approach to modeling deformation in aluminum sheet materials using input from a variety of length scales. It demonstrates how information from electronic and atomistic level calculations can be used in calculations of engineering forming processes. …describe this work to a materials science and engineering professional with no experience in your technical specialty?This work provides an approach for using a variety of microstructural information into constitutive equations for metalforming. It describes the framework for linking atomistic calculations with finite element simulations of forming. …describe this work to a layperson?This work describes an approach whereby one can predict how changing the composition of a metal or its microstructure can influence the ability to make automotive parts.A multi-scale, computational design approach for aluminum sheet alloys, which includes key inputs from the electronic, atomistic, microstructural, and continuum length scales, is reviewed within the context of room and elevated temperature forming. Specific examples, which are aimed at improving aluminum sheet materials for automobile components, include prediction of flow curves from tensile testing, forming limit diagrams, and component forming.

Adhesion of nickel–titanium shape memory alloy wires to thermoplastic materials: theory and experiments

“…Along those lines, we suggest that improvements to cohesive models should include characterization of the NiTi surface topography at the micron level (see, for example, [84,85]), as well as atomistically informed cohesive laws that properly account for the chemistry and physics of the NiTi/organophosphorus/polymer interface. Indeed a numerical model could be developed that accounts for all of the aforementioned features of these composite materials within the spirit of a multiscale computational modeling and design [88]. The development of thermo-mechanical-based cohesive models that account for the effect of microgeometry, cyclic loads and temperature effects will be the focus of future work.…”

Experimental Study on Crashworthiness of Functionally Graded Thickness Thin-Walled Tubular Structures

“…It is also possible of those materials as energy absorbing tubular structures since they are competitive with common materials such as mild steel. However, the absorbers with aluminum material are still of prime importance in dissipating the impacting energy as they have high strength to weight ratio and high stiffness values [45], which is a primary reason why the aluminum alloy material is chosen herein. Those properties make it a befitting choice for crash absorbers.…”

A brief review of data-driven ICME for intelligently discovering advanced structural metal materials: Insight into atomic and electronic building blocks

“…For instance, the high-throughput-type and the combinatorial approaches integrating both the bottom-up designing and the top-down engineering set up the digital twin feature of compositionprocessing-structure-property-performance (CPSPP) workflow process at multiscales [17,18,19,20,21,22,23], which is known as the data-driven ICME [2]. The advanced structural metal materials are developed/manufactured crossing multiscales, from Electronics to Phases [24,25], i.e., from Atom to Autos [26], from CALPHAD to Flight [27]. Moreover, to lead the world in scientific and technological innovations, global competitors have launched various strategies/programs and boosted the development of new manufacturing technologies, which include the Materials Genome Initiative (MGI) [28] and the Advanced Manufacturing of United States [29], the China's Materials Genome Engineering (MGE) & Made in China 2025 [30], the European Union's Industry 4.0 Programme [31], the Industry 2050 of United Kingdom [32], the Intelligence Manufacturing System 2020 (IMS2020) & Toward Technology Innovation of Society 5.0 of Japan, the Industry Innovation 3.0 of Korea, and so on [2].…”
