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.

There is a fact we have to admit here, first, that is art innovation, since
its early beginnings, is mostly a male product, and causing to stir interest and
attention, if it was a female one. Psychiatrist and sociologists could give us a
convincing answer or a logical explanation for that. What is really important
here is how the male artist could review his vision to woman, what was the
impact of all these ideas and desires towards each other in their artistic
products? Did he reflect the real role played by the woman in pushing the
artist towards specific ways? Did it related to the struggle for immortality? In
searching for motherhood and life eternity and the partner to find the way to
life. We, often, find

Here we don't mean bees and plagiarism... It goes beyond the fact that traffic is made to the whims of those who write or write to it, or in it a little bit of truth and then be framed, to add exaggeration and exaggeration to it.

MDS code is a linear code that achieves equality in the Singleton bound, and projective MDS (PG-MDS) is MDS code with independents property of any two columns of its generator matrix.   In this paper, elementary methods for modifying a PG-MDS code of dimensions 2, 3, as extending and lengthening, in order to find new incomplete PG-MDS codes have been used over . Also, two complete PG-MDS codes over  of length  and 28 have been found.
