The design of wire-coating dies is described using finite element numerical analysis as a guide. Finite elements are able to accommodate awkward geometries and non-Newtonian fluid properties in a realistic manner, and produce streamline and stress patterns within the die. Two basic die geometries are examined and a new design which eliminates recirculation within the die is proposed. 相似文献

Multi-scale finite element modelling using bubble function method for a convection-diffusion problem
Due to the multi-scale nature of the convection-diffusion equation the standard Galerkin method fails to predict accurate and stable results. A multi-scale finite element method based on the bubble function approach has been developed and applied to this problem. Finite element formulations based on the discontinuous weighting functions including the streamline upwind Petrov-Galerkin (SUPG) method are also evaluated. The results show that the multi-scale method provides stable and accurate results and matches very well the analytical solution. 相似文献

An experimental and theoretical investigation is described on the effects of viscoelasticity and geometric and material nonlinearity in rubber-toughened graphite/epoxy adherends. Single-lap joints, with adherends of a matrix-dominated layup and a brittle epoxy adhesive layer, were tested under two constant loading rates to failure; axial strains were measured at several locations on the surface of the adherends. Aluminum and fiber-dominated laminate adherends were also studied for comparison. Finite element analyses of the adhesive joint were made using linear and nonlinear viscoelastic characterizations of the composite. The experimental work is discussed first. Then we describe the constitutive theory and its implementation in the finite element analysis, after which the theoretical ane experimental results are presented and compared. 相似文献

采用我国现行桥梁规范中最不利的三种环境温差作用(两种均匀温度变化和一种梯度温度变化),利用有限元软件ABAQUS对一种FRP-混凝土组合桥面结构进行热应力分析,得到了该组合桥面结构在这三种温差作用下的变形特征和应力分布状况。有限元模拟结果表明,均匀温度变化效应大于梯度温度变化效应;温差作用对FRP-混凝土组合桥面结构非常不利,在以后FRP-混凝土组合桥面结构设计中需将此作用作为重要的荷载之一加以考虑。 相似文献
