报告摘要:Deformation-based manufacturing is one of most practical and efficient manufacturing processes to fabricate net-shape or near-net-shape parts via plastic deformation of materials. Recently, this traditional manufacturing process has been being revitalized as many attractive and unique advantages and characteristics including high productivity and efficiency, superior mechanical properties, excellent material utilization, low production cost, and being able to fabricate the complex geometries and features of deformed parts cannot be replaced by other manufacturing process. With the ever-increasing costs of materials, energy, and manpower, more and more strict requirements from environment-friendly and sustainable development perspectives, and the marginal profit of this traditional manufacturing, the design of deformed parts, forming process, tooling and the entire forming system, as well as defect prediction, avoidance and the assurance and control of the deformation made product quality are becoming more and more critical. All of these are related to the initiation, growth and development of damage and fracture in manufacturing and further in product service. Therefore, an in-depth understanding of damage and fracture behaviors and an extensive insight into the formation and occurrence mechanisms of the damage and fracture is crucial. In this talk, the mechanisms of initiation, coalesce, growth and development of voids in plastic deformation, formation and occurrence of damage and fracture, behaviors of damage and fracture in multi-scaled deformation, prediction criteria of damage and fracture, and prediction and avoidance of damage and fracture related defects via modeling, simulation and analysis base on case studies will be presented. The talk will give an overview of the state-of-the-art in damage and fracture study.
