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.

复杂材料细观力学研讨会 2009 年 11 月 2 日至 3 日，加拿大温哥华 联合主席：Zhigang Suo ([e-mail]. 电话：617-495-3789) 联合主席：Wing-Kam Liu ([e-mail]. 电话：847-491-7094) 资助者：学术 Sinica，空军科学研究办公室，国家科学基金会题为“复杂材料的细观力学”的研讨会建议于2009年11月2日至3日在温哥华举行，由台湾中央研究院、美国空军科学研究办公室和美国国家科学基金会联合主办。 复杂材料，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。 例子包括极端条件下金属的断裂、插入反应引起的锂离子电池中的耦合质量传递和变形、聚合物响应不同刺激而发生的大变形和膨胀，以及复合材料在应力集中部位的渐进损坏。 在理解这种复杂行为背后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实质性进展。 然而，对微观过程的机械理解与工程材料和结构的合理设计之间存在差距。 缩小这一差距需要介观力学的根本进步。 该研讨会将对现代技术至关重要的研究领域的知识传播产生广泛影响。 将努力邀请年轻、女性和少数民族研究人员参加。 还将努力邀请来自美国和亚洲的参与者。 该研讨会将汇集对复杂材料的变形和断裂以及细观力学的基本作用有着共同兴趣的研究人员。
