NSF Workshop on Life Performance of Polymer Based Engineering Materials: The Interaction Between Mechanics and Chemistry; Washington, DC; Fall 2013

将召开一次以聚合物为基础的工程材料(LPPEM)的寿命性能研讨会：力学和化学之间的相互作用。聚合物目前被大量应用于工程应用中，其中聚合物基材料的失效可能会产生严重的后果。聚合物的时间相关性质通常是这些先进工程应用中的关键方面。化学和力学之间的相互作用是预测这些材料的寿命性能的关键挑战。LPPEM讲习班的目标是将力学和化学界的研究人员聚集在一起，以确定在实验和计算两方面推进方法学所需的需求和知识差距。将这些往往不同的学科结合在一起将在智力上具有挑战性，并应刺激在领域接口上开发新的研究想法和方法：这些想法和方法可能在个别研究领域内也具有价值。改进、合理和可靠的聚合物和聚合物复合材料寿命预测方法的开发将为美国的技术基础设施带来重要好处，包括(I)提高现有材料在新应用中的利用率，(Ii)有效设计和更快速地部署新材料。通过阐明研究挑战和机遇，LPPEM研讨会将开始确定潜在的方法，以更快地开发、部署和验证聚合物材料的寿命性能，这些材料对21世纪的先进工程应用越来越重要。

A workshop will be convened on Life Performance of Polymer based Engineering Materials (LPPEM): The Interaction between Mechanics and Chemistry. Polymers are currently used in a large number of engineering applications, where failure of the polymer based materials can have significant consequences. The time dependent properties of the polymer is typically the critical aspect in these advanced engineering applications. The interplay between chemistry and mechanics is a key challenge in predicting the life performance of these materials. The objective of the LPPEM workshop is bringing together researchers from the mechanics and chemistry communities to identify the needs and knowledge gaps required to advance the methodologies in both experimental and computational fronts. Bringing these often disparate disciplines together will be intellectually challenging and should stimulate the development of new research ideas and approaches at the domain interfaces: ideas and approaches that may also have value inside the individual research domains. The development of improved, rational and robust methods for predicting the life performance of polymers and polymers composites will have important benefits for the US technical infrastructure, including both (i) improved utilization of existing materials in new applications and (ii) effective design and more rapid deployment of new materials. By elucidating research challenges and opportunities, the LPPEM workshop will begin the process of identifying potential approaches for the more rapid development, deployment and validation of the life performance of polymeric materials that are increasingly important for advanced engineering applications in the 21st century.
