Design of Composite Structures Using Advanced Numerical Tools

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....

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Design of Stable Stabilizing Regulators Using Advanced Visualization Tools

The well known Diophantine equation based solution for stabilizing and pole placement technique for open-loop unstable discrete-time time-delay plants, has some limitations optimizing the regulatory properties of the closed-loop. An iterative algorithm is introduced to optimize these regulators. Advanced visualization tools can help to find the stable stabilizing controllers.

Design of a Microstrip Bandpass Filter Using Advanced Numerical Models

Advanced numerical linear circuit models for parallel microstrip coupled line sections have been developed by Applied Wave Research (AWR) for use with their Microwave Office simulation program. The linear elements incorporate closedform solution techniques that may be evaluated with a linear circuit simulator. The response of the elements provides a high degree of accuracy with respect to elect...
