Plasmonics of 3-D Nanoshell Dimers Using Multipole Expansion and Finite Element Method

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....

Numerical Reconstruction of Permeability Material Using 3-D T -Ω Formulation of Finite Element Method

Three-Dimensional electromagnetic numerical modelling is used in inversion problems, commonly for determining the distribution of electrical parameters such as conductivity or permeability. This type of problems is a non-linear and ill-conditioned problem needs two phase resolutions: the forward and the inverse phase. In this paper we describe a numerical approach to image the electrical permea...

Robust and scalable 3-D geo-electromagnetic modelling approach using the finite element method

Numerical modelling of 3-D hard turning using Arbitrary Eulerian Lagrangian finite element method

In this paper, 3-D Finite Element Method (FEM) based numerical modelling of precision hard turning has been studied to investigate the effects of chamfered edge geometry on tool forces, temperatures and stresses in machining of AISI 52100 steel using low-grade polycrystalline cubic boron nitrite (PCBN) inserts. An Arbitrary Lagrangian Eulerian (ALE) based numerical modelling is employed for 3-D...

Novel Axial Flux Brushless Resolver Analysis and Optimization Using 3D Finite Element and d-q Model Method

Resolvers are widely used in electric driven systems especially in high precision servomechanisms. Both encapsulated and pancake resolvers suffer from a major drawback: static eccentricity (SE). This drawback causes a significant increase in resolver output position error (RPE) which could not be corrected electronically. To reduce RPE, this paper proposes a novel structure with axial flux. Pr...
