MECHANICAL TESTING OF METALS AND POLYMERS By (name) Subject Instructor Institution Date 1. Introduction This report documents the laboratory procedures done on various engineering materials comprising ferrous metal and polymers. The ferrous metal investigated in this study was steel with carbon content in the range of between 0.1% and 0.85%…
The most efficient way to handle such problems is to recycle these wastes for re-use. As there are numerous substances that lead to environment pollution, the methods of recycling these wastes for re-use becomes important. This article intends to analyse the recycling methods and the end products of two prominent household items like plastic and E wastes.
The experiment was because a materials mechanical property is extremely dependent to the materials chemical composition. The experiment was then sought to strengthen the fact by caring out test on steel’s and polymers mechanical properties, which included tensile strength, hardness, impact test, percentage elongation, and the yield strength.
Mount the specimen in the machine and subject it to tension. The tensile force is recorded as a function of the increase in gage length. Engineering stress or nominal stress, s, is defined as S=F/Ao where F-tensile force and Ao-cross section area of the gage section, while the engineering strain, or nominal strain, e, is defined as e=?
The axial strain in a body subjected to a direct tensile or compressible stress is always accompanied by an opposite kind of strain in all directions at right angles to each other; hence, the body undergoes two types of
The author states that a chassis material is usually made out of steel and aluminum alloys. The chassis material must demonstrate an increase in strength by the action of paint baking after press-forming step. The material of the chassis is next chosen, and the material cut using high quality cutters; for example plasma and laser cutters.
fail to end up in fracture based on the applied magnitude of the force (International Conference on Civil Engineering and Material Engineering & In Zhang et.al, 2012).
The ductility’s property is somewhat directly related to that of toughness, even though the latter is often
According to (O’Brien,2002,pg -291 ) “When brittle materials fracture, they shatter. However, ductile materials demonstrate a much wider range of fracture behaviors. This wider range of behaviors arises due to the interaction of
It refers to the point during the application of stress on a material at which the material fails and thus breaks. From this point, the curve starts going down indicating that a small increment of little strain requires a relatively smaller stress.
Fracture refers to the
A stapler has different parts, and these parts include the body, base with the anvil, staple’s magazine, leaf spring, helical coil spring, raceway, rear pin joint, blade and staple exit. The illustrations below show the parts of the stapler
