A Workshop onMeso-scale mechanics of complex materials2 and 3 November 2009Vancouver, CanadaCo-Chair: Zhigang Suo ([e-mail]. Phone: [phone])Co-Chair: Wing-Kam Liu ([e-mail]. Phone: [phone])Sonsors: Academic Sinica, Air Force Office of Scientific Research, National Science FoundationA Workshop titled ?Meso-scale Mechanics of Complex Materials? is proposed, to be held in Vancouver, on 2 and 3 November 2009, jointly sponsored by Academia Sinica (Taiwan), Air Force Office of Scientific Research (USA), and National Science Foundation (USA). Complex materials, such as metallic alloys, ceramics, polymers, and composites, exhibit highly nonlinear mechanical behavior. Examples include fracture of metals under extreme conditions, coupled mass transport and deformation in lithium-ion batteries caused by insertion reactions, large deformation and swelling of polymers in response to diverse stimuli, and progressive damage of composites at sites of stress concentration. Substantial progress has been made in understanding microscopic processes underlying such complex behavior, and in using these materials in engineering structures. A gap, however, exists between mechanistic understandings of microscopic processes and rational design of engineering materials and structures. Closing this gap will require fundamental advance in meso-scale mechanics. The Workshop will have a broad impact on knowledge dissemination of a field of research essential to modern technologies. Effort will be made to invite participants among young, as well as female and minority, researchers. Effort will also be made to invite participants both from the United States and Asia. The Workshop will draw together researchers who share common interests in the deformation and fracture of complex materials, and in the fundamental roles of the meso-scale mechanics.

复杂材料的研讨会机制2和2009年11月3日，加拿大椅子：Zhigang suo（[e-mail]。电话：617-495-495-3789）共同椅子：wing-kam liu（[e-mail]）国家科学研究办公室，国家科学研究办公室，名为“复杂材料的中级机械师”的美国科学研究办公室？建议于2009年11月2日至3日在温哥华举行，由空军科学研究办公室（美国）和国家科学基金会（美国）共同赞助。 复杂的材料，例如金属合金，陶瓷，聚合物和复合材料，表现出高度非线性的机械行为。 例子包括在极端条件下金属的裂缝，由插入反应引起的锂离子电池的耦合质量转运和变形，聚合物对多种刺激的反应，以及聚合物的大变形和肿胀以及在应力浓度部位对复合材料的逐渐损害。 在理解这种复杂行为的基础的微观过程以及在工程结构中使用这些材料方面，已经取得了重大进展。 然而，在微观过程的机理理解与工程材料和结构的合理设计之间存在差距。 缩小此差距将需要在中级机械师中进行基本进步。 研讨会将对现代技术必不可少的研究领域的知识传播产生广泛的影响。 将努力邀请年轻，女性和少数群体研究人员中的参与者。 还将努力邀请美国和亚洲的参与者。 研讨会将汇集研究人员，这些研究人员在复杂材料的变形和断裂以及中级机械师的基本作用方面具有共同的兴趣。
