Acquisition of Instrumentation for Research on Component Failure Under High Temperature, Mechanical, and Environmental Stress

9977735 Kumosa该项目支持获得高温轴向和扭转机械强度测试，用于涉及机械工程、物理、材料科学和电气工程等学科的研究。该设备将用于确定复合材料和压实材料的可靠性，识别故障模式，并将利用轴向和扭转机械强度测试系统研究整形外科植入物的测试和结构化复合材料的表征。要采集的轴向振动损失单元将包括一个温度控制的样品室(-2000F至10000F)，其设计使得被测部件上的夹具以及部件将处于温度。这一能力将用于开发加速老化测试，从而增加该系统上组件的吞吐量。轴向和扭转应力的能力将使组件能够准确测试，如高压复合绝缘子、整形植入物和使用压实材料的各种设计，在这些设计中，扭转载荷下的故障也很重要。该仪器还将用于支持以下领域的研究：复合材料、压实材料和生物力学植入物在各种热、机械和环境条件下的分析，以及非侵入性监测技术的评估，例如使用衍射颗粒作为应变传感器在复合材料中原位测量部件在热、机械和/或环境应力下的完整性。收集到的实验数据将用于分析模型的精炼，以实现对新的复合材料和压实材料设计的准确模拟。这是MRI计划支持的设备补助。*

9977735KumosaThis project supports the acquisition of the high temperature axial and torsional mechanical strength testing for research involving the disciplines of mechanical engineering, physics, material science, and electrical engineering. The equipment will be used to determine the reliability of composites and compacted materials, identify failure modes, and testing orthopedic implants and characterization of structured composite materials will be studied using the axial and torsional mechanical strength testing system. The axial horsional lost unit to be acquired will include a temperature-controlled sample chamber (-2000F to 10000F), designed such that the grips on the component under test as well as the component will be at temperature. This capability will be used to develop accelerated aging tests, increasing the throughput of components on this system. The capability for axial and torsional stress will enable accurate testing of components, such as high-tension composite insulators, orthopedic implants and various designs using compacted materials where failures under torsional loads are also of importance. The instrument will also be used to support research in the following areas: the analysis of composites, compacted materials, and biomechanical implants under various thermal, mechanical, and environmental conditions, and the evaluation of noninvasive monitoring techniques, such as the use diffracting particles as strain sensor in composites for in-situ measurements of the integrity of components under thermal, mechanical, and/or environmental stresses. The experimental data collected will be used as analytical models that have been developed are refined to enable accurate simulation of the new composite and compacted materials designs. This is an equipment grant supported under the MRI Program.***
