    • Systems and methods for analyzing structural test data are disclosed. In one embodiment, a method includes applying a sequence of loads to a test article, receiving raw test data indicative of the applied loads from at least one sensor operatively associated with the test article, receiving predicted test data indicative of the predicted loads on the test article, filtering out invalid test data, cycle counting to pair loads in the test data, performing a first fatigue damage computation based on the raw test data, performing a second fatigue damage computation based on the predicted test data, and comparing the first and second fatigue damage computations. The filtering, cycle counting, and performing of the first and second fatigue damage computations, and the comparison of the first and second fatigue damage computations, may be performed simultaneously using a spreadsheet program.

    • Material properties such as stress in a ferromagnetic material may be measured using an electromagnetic probe. While generating al alternating magnetic field in the object, and sensing the resulting magnetic field with a sensor, the signals from the magnetic sensor may be resolved into in-phase and guadrature components. The signals are affected by both geomaterical parameters such as lift-off any by material properties, but these influences may be separated by mapping the in-phase and quadrature components directly into material property and lift-off components, and hence a material property and/or the lift-off may be determined. The mapping may be represented in the impedance plane as two sets of contours representing signal variation with lift-off (A) (for different values of stress) and signal variation with stress (B) (for different values of liftoff), the contours of both sets (A, B) being curved. The stress contours (B) at a constant angle. Hence calibration measurements taken along a few contours of each set enable.
    • 诸如铁磁材料中的应力的材料特性可以使用电磁探针来测量。 当在物体中产生交变磁场并且用传感器感测所得到的磁场时,来自磁传感器的信号可被分解为同相和脉动分量。 这些信号受到地质参数的影响,例如通过材料性质的剥离,但是这些影响可以通过将同相和正交分量直接映射到材料性质和剥离部件中而分离,因此材料性质和/ 或者可以确定剥离。 映射可以在阻抗平面中表示为两组轮廓,表示具有提升(A)(对于不同的应力值)和信号随应力的变化(B)的信号变化(对于不同的提升值),轮廓线 两组(A,B)均弯曲。 应力轮廓(B)以恒定角度。 因此,沿着每组的几个轮廓进行的校准测量使能。
