Experimental and Analytical Study of Bending Stresses and Deflections in Curved Beam Made of Laminated Composite Material
...Show More Authors

Abstract

 

Theoretical and experimental methodologies were assessed to test curved beam made of layered   composite material. The maximum stress and maximum deflection were computed for each layer and the effect of radius of curvature and curve shape on them. Because of the increase of the use of composite materials in aircraft structures and the renewed interest in these types of problems, the presented theoretical assessment was made using three different approaches: curved beam theory and an approximate 2D strength of material equations and finite element method (FEM) analysis by ANSYS 14.5 program for twelve cases of multi-layered cylindrical shell panel differs in fiber orientations and number of layers. One case of E-glass composite material was experimentally made and tested to verify the relation between applied load and maximum deflection and four  models were made of poly carbonyl to determine stresses under bending loads in polar scope, all results were compared with each other, the percentage accuracy was very good. The curved beam theory and strength of material equation formulas results were reasonable for the bottom surface, while it seems not enough for the top surfaces. Also, results explained positions and cases more affected by delaminating and the most preferred part of ellipse shape beam in resisting loads.

The novel in its construction depends on set of life elements that is employed by the writer or the novelist to create a convincing world that resemble the real life world and as the novel is going toward experimentation and employing modern phenomenon we find the novelist tends to take advantage from the most realistic details to achieve the required convincing state through serious situations and the novelist Maysaloun Hadi depended in writing her novels on creating tight relations between the things and the elements that has inspired her which are mostly from the environment and from reality , as an example of these elements is the old inherited traditions that distinguish Iraq society as this element is a very important point in Iraq

أشكالية توظيف الخطاب السياسي ودوره في تعزيز السلم المجتمعي: العراق انموذجا

لكل دولة في هذا العالم خطابها السياسي والذي يحدد سياستها الداخلية والخارجية، وهي سياسة ثابتة تنطلق من مفاهيم وبرامج وثوابت تخدم مصالحها الحيوية، لكون الخطاب السياسي ليس مجرد كلام عابر في عالم السياسة الدولية وانما هو ثوابت مهمة يحدد توجهات هذه الدولة او تلك ويحدد دورها الدولي وطبيعة العلاقة مع البلدان الاخرى ومنها الدول المجاورة لها. شهد العراق بعد العام 2003 تحديات جديدة تمثلت بتغليب خطابات الطائفية والكراه

literary arts and persuasions, in Mqamth cash cash Antzmtha three criteria: the
standard of Islam and the standard time, and Maaartadd purposes of poetry. This
has had its effect on lighting stand many of the goals of the poets and their
attitudes.
The first criterion: Those who study the positions of Alsergsti to poetry and
poets must be discerned his money comes from the spirit of Islam as a religion and

When we study the history of dentistry we can investigate some methodology styles which  lead us to psychology – dentistry or take the relationship between psychology and dentistry, and this type of specialization  which is Medical psychology has its own methodology and subjects, as the historical sequence in this filed lead to how evolution occurred in this branch of medicine, which was accompanied by many factors , and this factor that contributed to the consolidation of the misconceptions about the social, family and the media culture and gave a distorted picture of Dentistry and the attending physician or dentist  and show  him as someone tough , ruthless and violent in his dealings and style , these pro
