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.

تعد اللغة العربية العامة من المواد التي تدرسها الطالبات في الصف الأول في كل أقسام كلية التربية للبنات، وقد لاحظ الباحث إن الطالبات يفتقرن الى التعرف الى معاني كثير من الكلمات التي ترد في المقطوعات الأدبية الشعرية منها والنثرية التي يقدمها أستاذ المادة، وبما إن وقت المحاضرة محدود فأنه لا يسمح بالتعرف الى أفكار الطالبات حول معاني هذه الكلمات وقد يضطر الأستاذ أخيرا الى تقديم المعاني جاهزة للطالبات من اجل

Islam has paid great deal of attention to land issue where has been
considered most resources for providing Muslims with water and food and
building on that we notice that the Islamic government worked hardly to give
attention ton the land especially newly included under control of Muslims
especially that they had got with out fighting or bloodshed but had been
included via reconciliation with the landlords so the Muslims had share in that
would be taken either in cash or in materials in a value would be differentiated
following several issues like type of harvest and method of watering the land
and religion of the landlords.
So Muslims had listed laws and rules that enable them typical investment

The Morals Strategies from Sunnah Depending
...Show More Authors

The study aims at elicitation the morals strategies from sunnah depending on the analytic-qualitative method. It revealed a comprehensive integrated system of creative strategies to improve morals. It was categorized into three areas: cognitive strategies, affective strategies, and some strategies based on self-initiative and practice. The researcher recommended that teachers and educators should employ these effective strategies in the process of moral guidance for the Muslim generation. He also recommended that researchers should put more effort to do more In-depth qualitative studies, which must be directed to establish the origin of different education strategies from the Holy Qur’an, the Sunnah, and Muslim scholars’ legacy.

The poverty in the developing countries is output to under development as we consider welfare, where as when the poverty disappear that produced be the general development . Historically, in our countries, the underdevelopment is the result of colonialism period and what is associated with it of transferring the surplus abroad  and the disorder of production structure.  And at the present  time, the poverty is reproduced and aggravated in the last years as a result of many  internal and external reasons.Today, poverty is associated in many forms with the poverty previously.
