Design Sensitivity Analysis and Optimization of High Frequency Radiation Problems Using Energy Finite Element Method and Energy Boundary Element Method

This paper presents a continuum design sensitivity analysis (DSA) and optimization of high frequency radiation problems using the Energy Finite Element Method (EFEM) and Energy Boundary Element Method (EBEM). The noise radiated from the vibrating structure at a high frequency range is obtained through a sequential procedure. The structural EFEM calculates structural energy distribution, which i...

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....

Second order sensitivity analysis for shape optimization of continuum structures

This study focuses on the optimization of the plane structure. Sequential quadratic programming (SQP) will be utilized, which is one of the most efficient methods for solving nonlinearly constrained optimization problems. A new formulation for the second order sensitivity analysis of the two-dimensional finite element will be developed. All the second order required derivatives will be calculat...
