MECHANICAL PROPERTIES OF METALS

              The term property may be defined as the quality, which defines the specific characteristics of a metal. Study of all the properties of a metal provides a sound basis for predicting its behavior in manufacturing shop and also in actual use. The following properties of a metal are important for an engineer, to enable him in selecting suitable metals for his various jobs.
                     The mechanical properties of a metal which are completely define its behavior under the action of external loads or forces. Or mechanical properties are those properties which are associated with its ability to resist failure as well as behavior under the action of External forces. A sound knowledge of these properties is very essential for an engineer to enable him in selecting a suitable metal for his various structures or various components of a machine. Through there are many mechanical properties of a metal, an engineer should know, yet the following are important form the subject point of view
v  Strength
·         Tensile strength
·         Compressive strength
·         Specific strength
·         Shear strength
·         Yield strength
v  Stiffness

Pro/ENGINEER Functionality

Image
    Pro/ENGINEER Functionality The basic functionality of Pro/ENGINEER is broken into four major areas: •          Part Modeling and Design •          Assembly Modeling and Design •          Design Documentation (Drawing Generation) •          General Functionality                                 Part Design and Modeling Defining Geometry - Feature-Based Design • Create sketched features including protrusions, cuts, and slots made by either extruding, revolving, or sweeping along a 2D sketched trajectory, or blending between parallel sections  • Create pick and place features, such as holes, shafts, chamfers, rounds, shells, regular drafts, flanges, ribs, etc.  • Sketch c...

PATTERNS

PATTERNS:              From the design, provided by an engineer or designer, a skilled pattern maker builds a pattern of the object to be produced, using wood, metal, or plastic; other materials to be used can be polystyrene or even sand strickled into shape. The metal to be cast will contract during solidification, and this may be non-uniform due to uneven cooling. Therefore, the pattern must be slightly larger than the finished product, a difference known as contraction allowance. Pattern-makers are able to produce suitable patterns using ‘contraction rules’. Different scaled rules are used for different metals because different metals/alloys contract at different rates. Patterns also have core prints; these create registers within the moulds, into which are placed sand cores. Sand cores are used to create undercut profiles and holes which cannot be moulded.                  Paths for the entrance of...

Mechanical behavior of Al-Sic-Zn-Cu Metal Matrix Composite

                     Aluminum is the world‘s most abundant metal and is the third most common element, comprising 8% of the earth’s crust. The versatility of aluminum makes it the most widely used metal after steel. After iron, aluminum is now the second most widely used metal in the world. This is because aluminum has a unique combination of attractive properties. Low weight, high strength, superior malleability, easy machining, excellent corrosion resistance and good thermal and electrical conductivity are amongst aluminum’s most important properties. Aluminum is also very easy to recycle. A unique combination of properties makes aluminum and its alloys one of the most versatile engineering and construction material available today. A metal matrix composite (MMC) is composite material with at least two constituent parts, one being a metal. MMCs are made by dispersing a reinforcing material into a metal matrix. The matrix is the ...
