Generative design of stiffened plates based on homogenization method

نویسندگان

چکیده

Stiffened plates are widely used in aerospace structures as load-bearing components. In order to obtain a novel design of stiffened with excellent performance, generative method (GDMSP) based on the homogenization is proposed this paper, which optimizes stiffener layout an equivalent model. Then, detailed model can then be obtained by extracting path from discrete distribution angles. Moreover, optimized size optimization Two examples illustrate framework, including stiffness maximization rectangle plate and buckling load square plate. The configurations characterized streamlines uniform lines, respectively. For first example, has improvement 17%. second improves 35%. Results indicate that effectively provide for plates. results have clear noticeable directly establish

Analysis of Rectangular Stiffened Plates Based on FSDT and Meshless Collocation Method

In this paper, bending analysis of concentric and eccentric beam stiffened square and rectangular plate using the meshless collocation method has been investigated. For detecting the governing equations of plate and beams, Mindlin plate theory and Timoshenko beam theory have been used, respectively, with the stiffness matrices of the plate and the beams obtained separately. The stiffness matric...

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....

Finite element analysis of stiffened plates

The paper presents the development of a new plate/shell stiffener element and the subsequent application in determine frequencies, mode shapes and buckling loads of different stiffened panels. In structural modelling, the plate and the stiffener are treated as separate finite elements where the displacement compatibility transformation takes into account the torsion – flexural coupling in the s...

Buckling of functionally graded stiffened and unstiffened plates using finite strip method

This paper deals with local buckling analysis of rectangular functionally graded material plates using finite strip method and based on classical plate theory. The modulus of elasticity of the plate is assumed to vary according to a power-law distribution in terms of the volume fractions of the constituents. The principle of minimum total potential energy is employed to obtain stiffness and sta...

Incremental explosive analysis and its application to performance-based assessment of stiffened and unstiffened plates

In this paper, the dynamic behavior of square plates with various thicknesses and stiffening configurations subjected to underwater explosion (UNDEX) are evaluated through a relatively novel approach which is called Incremental Explosive Analysis (IEA). The IEA estimates the different limit-states and deterministic assessment of plats’ behavior, considering uncertainty of loading conditions and...
