This Faculty Early Career Development (CAREER) proposal is concerned with the creation of a new breed of computational solid mechanics tools based on embedding the solid geometry in arbitrary meshes, known as immersed boundary methods. The transition from the description of a structural component to a numerical model is more-often-than-not the bottleneck that hinders analysis from becoming an integral part of the design cycle. The first outcome of this proposal is a comprehensive set of tools that streamlines the path from a geometric description containing structural components such as solids and shells to the analysis of its mechanical performance. The second contribution emanates from an application of these tools to study the dynamic mechanical behavior of cracks driven by a pressurized fluid.The outcome of this work provides solutions to problems common to health, industrial and homeland security applications, and an explicit effort will be made to transfer the new tools to interested parties in the scientific, defense or industrial areas. Fluid-driven cracks are of interest to the energy and mining industries for their implications on oil and gas reservoir management, and in carbon sequestration, a promising technique to ameliorate global warming. A comprehensive educational plan is proposed, whose central idea is to foster science interest at middle school, with an estimated impact of 30,000 children. The plan revolves around training middle school teachers in exciting aspects of nanotechnology and computation through a summer school, and in collaborating with its alumni to shape the content of a program of hands?on lectures for the students.

这个教师早期职业发展（CAREER）建议关注的是创建一种新的计算固体力学工具，其基础是将固体几何嵌入任意网格中，称为浸入边界方法。从结构部件的描述到数值模型的转换往往是阻碍分析成为设计周期不可分割的一部分的瓶颈。该提案的第一个成果是一套全面的工具，简化了从包含固体和壳体等结构部件的几何描述到分析其机械性能的路径。第二个贡献来自于这些工具的应用，以研究裂纹的动态力学行为驱动的加压流体，这项工作的结果提供了解决问题的共同健康，工业和国土安全的应用，并明确的努力，将转让新的工具，在科学，国防或工业领域感兴趣的各方。流体驱动的裂缝是能源和采矿业感兴趣的石油和天然气储层管理，并在碳封存，一个有前途的技术，以改善全球变暖的影响。提出了一项综合教育计划，其中心思想是在中学培养科学兴趣，估计将影响3万名儿童。该计划围绕培训中学教师在纳米技术和计算的令人兴奋的方面通过暑期学校，并在与校友合作，以塑造一个程序的手的内容？为学生们做讲座
