REG: A New Interference Optical Strain Gage Rosette Technique

9409878 Li这项研究设备补助金将使西密歇根大学工程与应用科学学院的机械与航空工程系能够在承受轴向和扭转载荷的缺口试样表面的应力集中处，开发一种平面应变测量方法，即在小标距长度上测量剪切应变和两种法向应变。 这种新的应变测量系统将扩展当前的应变测量技术，允许测量表面的三种应变。 为了开发将导致改进的机械测试能力的有价值的多用途应变测量技术，这种系统是非常期望的。 ***

9409878 Li This Research Equipment Grant will make it possible for the Department of Mechanical and Aeronautical Engineering in the College of Engineering and Applied Sciences at Western Michigan University to develop an in-plane strain measurement shear strain and two normal strains over small gage lengths at stress concentrations of the surfaces of notched specimens subjected to both axial and torsional loadings. This new strain measuring system will extend current strain measurement techniques to allow measurement of three stains at surfaces. Such a system is highly desirable in order to develop a valuable multi-purpose stain measuring technique that will lead to improved mechanical testing capabilities. ***
