A Workshop on Meso-scale Mechanics of Complex Materials

2009年11月2日和3日，加拿大温哥华，复杂材料的介观尺度力学研讨会联合主席：索志刚（suo@seas.harvard.edu. 电话：617-495-3789）共同主席：刘永锦（w-liu@northwestern.edu. 电话：847-491-7094）传感器：中央研究院，空军科学研究办公室，国家科学基金会一个研讨会题为？复杂材料的细观力学建议于2009年11月2日至3日在温哥华举行，由中央研究院（台湾）、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。 复杂材料，如金属合金、陶瓷、聚合物和复合材料，表现出高度非线性的力学行为。 例子包括极端条件下的金属断裂，插入反应引起的锂离子电池中的耦合质量传输和变形，聚合物响应于不同刺激的大变形和溶胀，以及应力集中部位的复合材料的渐进损伤。 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的进展。 然而，在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着差距。 缩小这一差距需要在中尺度力学方面取得根本性进展。 讲习班将对传播对现代技术至关重要的一个研究领域的知识产生广泛影响。 将努力邀请年轻、女性和少数族裔研究人员参与。 还将努力邀请来自美国和亚洲的与会者。 该讲习班将吸引在复杂材料的变形和断裂以及细观尺度力学的基本作用方面有共同兴趣的研究人员。

A Workshop onMeso-scale mechanics of complex materials2 and 3 November 2009Vancouver, CanadaCo-Chair: Zhigang Suo (suo@seas.harvard.edu. Phone: 617-495-3789)Co-Chair: Wing-Kam Liu (w-liu@northwestern.edu. Phone: 847-491-7094)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.
