Strength of Materials Laboratory

          One of the principle concerns of an engineer is the analysis of materials used in structural applications. The term structure refers to any design that utilizes materials that support loads and keeps deformation within acceptable limits. Designing machines, structures, and vehicles, which are reliable as well as safe and cost effective, requires a proper knowledge of engineering as well as material selection.

In this laboratory, students will have the opportunity to apply loads to various materials under different equilibrium conditions. The student will perform tests on materials in tension, torsion, bending, and buckling. These conditions and/or constraints are designed to reinforce classroom theory by having the student perform required tests, analyze subsequent data, and present the results in a professionally prepared report.

EXPERIMENTS

1. Tension test and Young’s modulus of steel
2. Double shear test and bend test on mild steel specimens.
3. Hardhess test: Rockwell, Brinell and Vicker’s.
4. Torsion test: Rods and Flats.
5. Impact test: Charpy and IZad on metals.

Ductility test: Sheet metals (Al, GI and MS).

Manufacturing Technology Lab

FOUNDRY

 

Casting processes have been developed to suit economic production of cast products with desired mechanical properties, dimensional accuracy, surface finish etc. The various processes differ primarily in mold material (whether sand, metal or other material) and pouring method (gravity, pressure or vacuum). All the processes share the requirement that the material solidify in a manner that would avoid potential defects such as shrinkage voids, gas porosity and trapped inclusions. Any casting process involves three basic steps, i.e. Mold making, melting and pouring of metals into the mold cavity, and removal and finishing of casting after complete solidification.

EXPERIMENTS

1. Preparing a mould with solid pattern
2. Preparing a mould with split pattern

MACHINING PROCESSES (Lab I&II)

 

Machining is one of the processes of manufacturing in which the specified shape to the work piece is imparted by removing surplus material. Conventionally this surplus material from the workpiece is removed in the form of chips by interacting the workpiece with an appropriate tool. This mechanical generation of chips can be carried out by single point or multi point tools or by abrasive operations
