The anisotropy and nonuniformity of wood-plastic composites (WPCs) affect the milling tool, which rapidly wears during high-speed WPCs. Thus, evolution mechanism tool failure becomes complicated, prediction wear cannot be precisely described mathematically. A neural network based on test was proposed to predict condition traditional backpropagation (BP) easily falls into local optimal solution. genetic algorithm (GA-BP) model established by using GA optimise its initial weight threshold. BP...
DOI: 10.2514/1.41368 Hyperbolic heat conduction in a functionally graded hollow cylinder is investigated this paper. Except for uniform thermal relaxation time, all other material properties of the are assumed to vary along radial direction following power-law form with arbitrary exponents known as nonhomogeneity indices. When infinitely long, end effects can be ignored, and one-dimensional problem directionissolvedanalyticallyintheLaplacedomain.The...
Purpose This paper aims to examine the precision loss of ball screw raceway under different operating conditions and geometry parameters. Design/methodology/approach Based on a new coefficient K’ introduced especially for screws reflect actual contact condition, modified Archard theory is applied obtain wear volume ball-screw contacts. Thus, axial can be defined as ratio area. Meanwhile, novel running bench precision-measuring system are conducted. Precision variation obtained analyzed...
In this paper, the magnetoelectroelastic responses of radially polarized and magnetized hollow solid cylinders subjected to hygrothermal loading are obtained by a straightforward analytical method. The transversely isotropic homogeneous embedded with Winkler-type elastic foundation on inner and/or outer surfaces. assumed be infinitely long. To obtain temperature moisture concentration distributions within thicknesses cylinders, steady state, axisymmetric heat conduction diffusion equations...
The thermopiezoelectrical behavior of a functionally graded piezoelectric medium (FGPM) is investigated in the present work. For special case, dynamic response an FGPM rod excited by moving heat source studied. material properties are assumed to vary exponentially through length, except for specific and thermal relaxation time which held constant simplicity. governing differential equations terms displacement, temperature, electric potential obtained general form that includes coupled...
The transient thermal stresses around a crack in thermo-elastic half-plane are obtained under shock using the hyperbolic heat conduction theory. Fourier, Laplace transforms and singular integral equations applied to solve temperature stress fields consecutively. solved numerically asymptotic tip obtained. Numerical results show that have significant influence on dynamic field. It is suggested design materials structures against fracture loading, model more appropriate than Fourier model.
