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....
Attenuation Correction in SPECT during Image Reconstruction using an Inverse Monte Carlo Method: A Simulation Study
Introduction: The main goal of SPECT imaging is to determine activity distribution inside the organs of the body. However, due to photon attenuation, it is almost impossible to do a quantitative study. In this paper, we suggest a mathematical relationship between activity distribution and its corresponding projections using a transfer matrix. Monte Carlo simulation was used to find a precise tr...
متن کاملSimulation of Temperature Distribution in a Continuous Tunnel Reheat Furnace Using the Monte Carlo Method
A mathematical model of a continuous reheating furnace has been developed to identify the design and operating parameters that significantly affect furnace performance. In this study, the furnace is modeled 3 dimensionally and theMonte Carlomethod is used to find the overall absorption factor. The overall absorption factor is then used to calculate the energy balance for furnace walls, the gas,...
متن کاملAnalysis of Composite Laminates with Cut-outs and with Random Material Properties Using Fem and Monte Carlo Simulation
Abstract. Generally one encounters a substantial variation in the mechanical properties of composite laminates. This is due to the fact that a large number of parameters have to be controlled during the manufacturing process. The dispersion in the material properties can best be accounted for by modelling these as random. In this paper, FEM in conjunction with Monte Carlo Simulation is employed...
متن کاملMethod of Moments Using Monte Carlo Simulation
We present a computational approach to the method of moments using Monte Carlo simulation. Simple algebraic identities are used so that all computations can be performed directly using simulation draws and computation of the derivative of the log-likelihood. We present a simple implementation using the Newton-Raphson algorithm, with the understanding that other optimization methods may be used ...
