Microstructural Modeling of Ni-Al2O3 Composites Using Object-Oriented 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....

Deformable Object Modeling Using the Time-Dependent Finite Element Method

Continuum mechanics and the finite element method are used as basic tools to facilitate the animation of deformable objects. Two unique features in this paper are: (1) introduction of a framework for 3-D finite interface elements to deal with object interaction and (2) a simple approach to handle fracture propagation inside objects. Animation sequences have been constructed, and they indicate t...

Meso-scale Modeling of Tension Analysis of Pure and Intra-ply Hybrid Woven Composites Using Finite Element Method

One of the key issues associated with using of composites in various applications is their tensile behavior. The tensile behavior of a composite material is strongly influenced by the properties of its constituents and their distribution. This paper focuses on gaining some insights into the tensile process of pure and hybrid woven composite reinforced with brittle and ductile yarns. For this pu...

Object-oriented implementation of 3D DC adaptive finite- element method

In this paper, we introduced a clear objectoriented framework to implement the complicated adaptive procedure with C++ programming language. In this framework, it consisted of the unstructured mesh generation, a-posterior error estimating, adaptive strategy, and the postprocessing. Unlike the procedure-oriented framework, which is commonly used in DC resistivity modeling with FORTRAN language, ...
