Data-Driven Design for 3D Printed Materials with Tailored Fracture Response

断裂是材料失效的主要原因，可能造成严重的工程灾害甚至死亡。该项目旨在开发一个数据驱动的设计系统，该系统可以智能地优化异质结构的局部材料和结构，以获得所需的断裂响应，并提高其力学断裂性能，包括刚度、强度、韧性和破坏位移。它将在力学和数据驱动科学中开辟一个新的和有前途的研究领域，该领域涉及广泛的工程领域中棘手的逆问题。产生经济、高性能、定制化的3D打印结构材料，造福国家公司和企业，满足行业高端需求。

Fracture is the main source of material failure and may cause serious engineering disasters and even death. This project aims to develop a Data-Driven Design System that intelligently optimizes local materials and architectures for heterogeneous structures with desired fracture response, and enhancing their mechanical fracture properties including stiffness, strength, toughness, and failure displacement. It will open up a new and promising research field in mechanics and data-driven science that deals with intractable inverse problems in broad engineering fields. Economic, high-performance, and customized 3D printed structural materials will be generated to benefit national corporations and enterprises and meet the high-end industry needs.
