The aligned axonal fiber bundles in white matter make it suitable to be modeled as a transversely isotropic material. Recent experimental studies have shown that a minimal form, nearly incompressible transversely isotropic (MITI) material model, is capable of describing mechanical anisotropy of white matter. Here, we used a finite element (FE) computational approach to demonstrate the significance...
In this paper, the ANSYS is used to establish a three-dimensional model of brake drums, and then simulate the process of the brake drums' temperature rising through the forcing of boundary loads and initial conditions. After that the author reveal temperature field distribution of the brake drum brake element model, then verify the accuracy of model by an experiment, which lay a theoretical foundation...
In the process of aero-equipment design and manufacturing, mean time to repair (MTTR) is one of important maintainability parameters and it is required to conduct maintenance evaluation so as to verify equipment maintainability requirement. According GJB 2072 and MIL-STD-471 for aero-equipment maintenance evaluation, the number of samples should be no less than 30. However, it is almost impossible...
Propagation characteristics of surface acoustic waves (SAWs) in IDT/(100) AlN/diamond structures are analyzed in this study using the finite element method (FEM). The extracted coupling-of-mode (COM) parameters are employed to calculate the frequency responses of two-track SAW filters using the transmission matrix method. To enhance the sideband suppression, Chebyshev function is adopted to modify...
