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 use of story to convey educational content which serves particular purposes is common use long ago, such as we see in Quran`s stories and bible stories which consider good examples, therefore the story individuates by this mission which has magnificent influence minds of the readers.

It aims to reforms the Jewish individual avvording to it`s vision and thoughts.

The research titles “Ammorrite tribes and their historical role in Mesopotamia and Levant” deals with tribe structure, nomination, political and cultural roles of these tribes in Mesopotamia and Levant, as it terminate Sumerian presence in Iraq and changed historical course and contributed in changing population landmarks and started new bright era, in addition to admitting new beliefs, gods and laws, beside ruling principles which became tribal, i.e., dynasties instead of Sumerian rulings based on religion belief.

Seemed reflections of cultural globalization are clear on the values of communities those values that preserve each community privacy, so that became members of these communities lack the ability to distinguish clearly between what is right and what is wrong and adoption of ideas and values imported from abroad, regardless of whether positive or negative. The aim of the research was to: - 1 - Detection of cultural globalization in the educational values for students kindergarten section. 2 - To identify the most prominent educational values (social, scientific, aesthetic, moral and spiritual) globalized culture.

The research aimed at measuring the degree to which the accept their class environment in governmental & civil Kindergartens &  it also aimed at knowing the differences between the dimensions of the measurement & the differences according to the kindergarten & class variables .

The researcher made a measurement for the class environment & it included five dimensions & the answering choices were three ( to a big extent , to some extent and no ) and after making sure that the measurement is usable , the researcher applied it on the sample which consisted of ( 212 )male & female children through the estimated answers of the teacher & the result was that there was an accep
