The desired form or final shape of the metal defines which type of deformation process has to be applied. Physical and mechanical properties of metal such as strength, hardness, brittleness, elasticity, plasticity, malleability, toughness, grain structure, isotropic behavior etc. also play an important role in deciding which kind of manufacturing process is to be used.
Metals are generally ductile materials with a large plastic range on stress strain curve. This is due to the metallic bond present in them (Askeland, 2009: 33). The stress strain curve of mild steel is shown here, (although it will be different for each metal, it will follow more or less the same pattern): The area after the yield point is the plastic range of mild steel. Clearly, it can undergo significant amount of plastic deformation before it finally fractures. Same is true for other materials. Hence, to form a material in to desired shapes, plastic deformation is a desirable process.
There are many different yield criteria which tell us the stress required to cause permanent yielding in a material. Out of these Tresca criterion is considered suitable for ductile materials (Marciniak et al., 2002: 20). It suggests that yielding occurs (or plastic deformation starts) at a point when shear stress crosses a certain limit.
Formability of a metal is its ability to deform in to desired shape or form without failure. Failure can be due to different physical phenomenon like shearing or necking etc. (Kalpakjian and Schmid, 2001: 424).
One of the earlier developed tests is Cupping Test. In this test, a steel ball or any circular profile made of steel is pressed against the sheet with uniform increment of stress. The depth to which the sheet can be deformed is a measure of its formability. This method however has its own limitations as the results obtained are specific to the test conditions.

Electrical Engineering
The post-baccalaureate degree is a qualification for advancing studies after the completion of an undergraduate degree according to Mittal (333). Taking a course in Engineering has been my special interest and aspiration since childhood. While still in primary school my teachers and parents had always claimed my potential to become an engineer.

Introduction to Mechanical Engineering
The United States Military Academy (1817), now called Norwich University and Rensselaer Polytechnic Institute (1825) were the first schools to offer education in engineering in the United States. All along, science and mathematics have been the basis for mechanical engineering education (Burstall 200).

Electrical engineering
I wrecked a few electronic items in the house and got in trouble; however, as I grew older I was a regular hand around the house and I did most of the repairs on electronic stuff. In high school, I researched about engineering and one of my mentors and uncle who works as an electrical engineer encouraged me to major in the sciences.

Mechanical Engineering- Mechanical Project
Making material choice remains an essential element for enhancing proper functioning of the structure, upon construction. The selection process for materials follows analysis of the functions for the proposed structure being constructed. The functions determine the required material strength among other properties; hence selection of material meeting structural requirements (Jones 1975).

Manufacturing Technology
The compressor blades are vulnerable to failures including hydrogen embrittlement and silica embedment. The manufacturing process of the blades include forging, material build-up and forging. After machining the blades are welded with the rotor. The bevel ends are preferred for welding between the blades and rotor due to the higher strength of butt-welds.
