U.S.-Australia Cooperative Research: Application of Magnetomechanical Modeling to the Rotation Method for Measuring Biaxial Stress

该奖项将资助德克萨斯州圣安东尼奥西南研究所仪器与空间研究部的Martin J. Sablik博士前往澳大利亚进行为期一个月的访问，与塔斯马尼亚大学的Richard Langman博士进行合作研究。研究的重点是建立一种新的应力测量模型。Sablik博士将利用他在磁机械滞回建模方面的经验来解释旋转法获得的结果，旋转法是朗曼博士发明的一种磁性技术，用于测量磁性材料中的应力，特别是在双轴应力的情况下。该项目的研究成果可用于铁路车轮应力的测量和油气管道应力的测量。这种应力测量对铁路和管道操作员最为有利，有助于发现可能导致破裂的高应力情况，从而能够及时采取补救行动。

9316679 Sablik This award will support the travel of Dr. Martin J. Sablik of the Instrumentation and Space Research Division of the Southwest Research Institute in San Antonio, Texas, for a one month visit to Australia in order to conduct collaborative research with Dr. Richard Langman at the University of Tasmania. The focus of the research is to develop a new model for stress measurement. Dr. Sablik will use his experience with magnetomechanical hysteresis modeling to account for results obtained with the rotation method, a magnetic technique originated by Dr. Langman for measuring stress in magnetic materials, in particular in cases of biaxial stress. The project results are expected to be useful for measuring stresses in railroad wheels and for measuring stresses in gas and oil pipelines. Such stress measurements would be most beneficial to railroad and pipeline operators in helping to detect high stress situations which might lead to rupture, and thereby enable timely remedial action to be taken.
