This document describes a finite element analysis of composite grid structures for use in skin stiffening applications. It provides background on grid structures, noting that they are shell-like structures that support the skin of a structure. When made of composites, grid structures can reduce weight and uniformly distribute loads for aerospace applications. The study aims to analyze an orthogrid and isogrid composite plate using FEA to evaluate deflection, stress, and stiffness-to-weight ratio when the skin thickness is varied. An overview of finite element analysis and the steps involved in an FEA are also provided.
MECHANICAL BEHAVIOUR OF COMPOSITE MATERIALS IN METALIAEME Publication
Composite materials have gained traction in the world today and are becoming of common use in industrial and specialized applications in general due to their flexible nature that involves mixing through layers or matrixes the components of various substances and therefore, a percentage of each substance’s physical properties. In recent years there has been an increasing concern for industries to use cost effective reinforcement for metal materials like aluminum which is abundant cheap, with various desirable properties like its lightness, but lacks the strength for various applications – ceramic materials such as SiC and aluminum oxide are used generally for reinforcing the aluminum MMC. There is a good probability, backed up by tests for certain materials, that reinforcing metals with composites can increase failure displacement, fatigue life, ultimate failure load and energy absorption capacity, amongst many others by substantial amounts.
The fabrication methodology of a composite part depends mainly on three factors:
(i) the characteristics of matrices and reinforcements,
(ii) the shapes, sizes and engineering details of products, and
(iii) end uses.
The composite products are too many and cover a very wide domain of applications ranging from an engine valve to an aircraft wing.
The fabrication technique varies from one product to the other.
Composites are engineered materials made from two or more constituents with different physical or chemical
properties, which remain separate and distinct within the finished structure. A fiber is a material, which is made into
a long filament with diameter generally in the order of 10 microns. The aspect ratio of length to diameter can be
ranging from thousands to infinity in continuous fibers. Increasing worldwide environmental awareness is
encouraging scientific research into the development of cheaper, more environmentally friendly and more
sustainable construction and packing materials. For environment concern on synthetic fiber (such as glass, carbon,
ceramic gibers etc) natural fibers (such as flax, hemp, jute, kenai) etc are widely used. Industrial hemp fiber is one
of the strongest of the natural fibers available and possesses benefits such as low cost and low production energy
requirements. The primary objective of this research is to fabricate the natural fiber composites with suitable
processing/manufacturing methods and to examine the mechanical properties when subjected to Tension, Bending
and to compare & contrast the results with the available literature. In this research work, hemp fiber reinforced
Epoxy matrix composites have been developed by hand layup method with varying process parameters, such as
coupling agent(with and without compatibilizers) and different fiber percentages (10%,20% and 30% by weight).
The developed composites were then characterized by tensile test and flexural testing. Results show that the tensile
strength and flexural properties increases with the increase in fiber percentage. However after a certain percentage
the tensile strength decreases again. Compared to untreated hemp fiber, no significant changes in the tensile strength
have been observed for treated hemp fiber reinforcement. The flexural strength / modulus of the composite were
higher compared to pure epoxy for all filler/fiber loadings.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
