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

断裂是材料失效的主要来源，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，智能地优化具有所需断裂响应的异质结构的局部材料和结构，并提高其机械断裂性能，包括刚度，强度，韧性和失效位移。它将在力学和数据驱动科学领域开辟一个新的和有前途的研究领域，处理广泛工程领域中的棘手逆问题。经济，高性能和定制的3D打印结构材料将产生，以造福国家公司和企业，并满足高端行业需求。

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.
