buckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
COMPUTER SIMULATION OF FLUID FLOW FILLING DURING MOLD USING FINITE VOLUME METHOD
In this investigation, ^5 2-D Finite Volume Method (FVM) with unstructured triangular mesh is developed to simulate the mould filling process. The simulation of fluid flow and track of free surface is based on the Marker And Cell (MAC) technique. This technique has capability ofhandling the arbitrary curved solid boundaries in the casting processes. In order to verify the computational results ...
متن کاملComparison of Introgression and Synthetic Breed Strategies for Litter Size Trait in Sheep using Computer Simulation
The objective of this study was to compare introgression and synthetic breed strategies for litter size trait improvement in sheep using computer simulation. For this purpose, a trait with heritability of 0.1, consisting of two chromosomes was simulated. On chromosome 1, a single QTL as the major gene was created that accounted for 40% of the total genetic variance. The effect of favorable and ...
متن کاملSimulation of Wave Propagation over Coastal Structures Using WCSPH Method
In this paper a space-averaged Navier–Stokes approach was deployed to simulate the wave propagation over coastal structures. The developed model is based on the smoothed particle hydrodynamic (SPH) method which is a pure Lagrangian approach and can handle large deformations of the free surface with high accuracy. In this study, the large eddy simulation (LES) turbulent model was coupled with th...
متن کاملSimulation of Lightning Surge Propagation in Transmission Lines Using the FDTD Method
power transmission lines. Numerical computation of solving the Telegraphist’s equations is determined and investigated its effectiveness. A source of lightning surge wave on power transmission lines is modeled by using Heidler’s surge model. The proposed method was tested against medium-voltage power transmission lines in comparison with the solution obtained by using Bewley lattice diagram. As...
