ABSTRACT

Corrosion, Stress Corrosion Cracking (SCC) and corrosion fatigue failures of high strength aircraft aluminums are costly and potentially catastrophic material problems affecting the aircraft fleet today. As the service lives of aircraft are extended, the increasing inspection and repair of corrosion in aging aircraft adversely affects fleet readiness, the cost of operation, and personnel safety. Shot peening (SP) is a wid ....etc

MECHANICAL PROPERTIES OF CONCRETE INCORPORATING USED
FOUNDRY SAND
ABSTRACT
Metal foundries use large amounts of the metal casting process. Foundries successfully
recycle and reuse the sand many times in a foundry and the remaining sand that is termed
as foundry sand is removed from foundry. This study presents the information about the
civil engineering applications of foundry sand, which is technically sound and is
environmentally safe. Use of foundry sand in various ....etc

IMPROVEMENT OF MECHANICAL PROPERTIES OF RIGID PAVEMENTS

INTRODUCTION
Transportation-basic infrastructure-development

Rigid and flexible

Basic neccesity-stable against loads

Rigid offers more strength “load

But change in temp. “warping up and warping down

To relieve stress-joint

Joint from the weaker plane and most of defects occur there

Increase the mechanical properties such as load carrying capacity and cracking resistance

Methods for improvement

Real estate market place “ Transacting properties online
PR-AP-B114
Background
The objective of the project is to design and develop one stop solution for trading properties online. It bridges the communication between real estate agents, Builders and retail buyers/sellers. The system can be used to store the profiles of agents, builders, buyers, sellers and the properties to be transacted. Buyers are the customers who buy new or resale properties where as sellers are builders (for new properties) or people resel ....etc

Abstract :

The case study project is significant since mild steel is used in structure, case hardening, gears, free cutting steels, shafting, forging etc. Mild steel plates were tested for mechanical properties like hardness, tensile strength, yield point etc. Later on the plates were joined by submerged arc welding and the mechanical properties were estimated again. Also weld ability, harden ability, tensile test etc. were conducted for the same result. ....etc
