The Materials Research Science and Engineering Center (MRSEC) at Brown University supports an interdisciplinary research program on the mechanics of materials at the atomistic and microstructural level. The research is carried out in one interdisciplinary research group, with appropriate seed projects. Within the IRG one major thrust is the study of the effect of stress on the performance of electronic nanostructures and nanodevices. This research has potential impact on understanding how stress effects the design and performance of atomic scale sized lasers and electronic devices. The experimental results are modeled using the quasicontinuum model developed at Brown. The second thrust in the IRG is concerned with the investigation of the micromechanics of materials with complex microstructures. Emphasis is on the interface between two types of systems such as bicrystals of aluminum, aluminum alloy, and synthetic bimaterials. Computational techniques closely support the experimental efforts. The center is engaged in a variety of educational activities, notably the development aterials science teaching modules aimed at the high school level and the training of secondary teachers in use of the modules. The Center supports well maintained shared experimental facilities, which are accessible to outside users and also supports interactive efforts with industry and other sectors.Participants in the Center include 17 senior investigators, 3 postdoctoral associates, 14 graduate students, 10 undergraduates, and 6 technicians and other support personnel. Professor Clyde L. Briant directs the MRSEC.

布朗大学的材料研究科学与工程中心(MRSEC)支持在原子和微观结构水平上的材料力学的跨学科研究计划。这项研究在一个跨学科的研究小组中进行，并有适当的种子项目。在IRG中，一个主要的推动力是研究应力对电子纳米结构和纳米器件性能的影响。这项研究对理解应力如何影响原子尺寸的激光器和电子设备的设计和性能具有潜在的影响。实验结果用Brown发展的准连续粒子模型模拟。IRG的第二个推力涉及对具有复杂微结构的材料的微观力学的研究。重点是两种类型的系统之间的界面，如铝、铝合金和合成双材料的双晶。计算技术密切支持实验工作。该中心从事各种教育活动，特别是针对高中阶段的材料科学教学模块的开发，以及对中学教师使用这些模块的培训。该中心支持维护良好的共享实验设施，这些设施对外部用户开放，并支持与行业和其他部门的互动努力。参与中心的人员包括17名高级研究员、3名博士后助理、14名研究生、10名本科生和6名技术人员和其他支持人员。克莱德·L·布莱恩特教授是MRSEC的负责人。
