Buckling and Fundamental Frequency Optimization of Tow-Steered Composites Using Layerwise Structural Models

High-fidelity Structural Optimization of a Tow-Steered Composite Wing

1. Abstract Composite materials are now making their way into the primary structures of large transport aircraft and have contributed to more efficient airframes. However, the composites used so far consist in conventional plies with fixed angles. The introduction of the capability to manufacture tow-steered composites opens the door to more efficient airframes by enabling more tailored structu...

High-fidelity Aerostructural Optimization of a High Aspect Ratio Tow-steered Composite Wing

In the last 30 years since their introduction into aerospace applications, composites have become increasingly used, making up as much as 50% of modern aircraft by weight. Considering this fact, it is surprising that most aircraft today are only scratching the surface of the true potential of composite technology with traditional uniaxial fibers. With the introduction of Automated Fiber Placeme...

High-fidelity Multipoint Aerostructural Optimization of a High Aspect Ratio Tow-steered Composite Wing

Composite materials have been playing a major role in modern aircraft design due to their high stiffness and strength to weight ratio. While the advantages of composite structures over their metallic counterparts is significant, it is possible to improve even further on the benefits offered by traditional composites through the use of novel composite manufacturing methods. One such method is au...

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....
