RESEARCH CENTRES/LABORATORIES

Research Centres

Research activities  include development in structural analysis and design; coastal and oceanographic processes; coastal and offshore structures; hydrology and water resources; transportation; public works; infrastructure materials and pavements; construction engineering and engineering management; geotechnical engineering; and geosensing systems engineering. Civil engineers have always been pioneers in testing adapting and using advnces in technology. Civil engineers apply computers, robotics, lasers, satellite imaging, remoate sensing, new materials and other developments to every aspect of their work.

Strength Of Materials Laboratory

In this laboratory, the parameters required for the design of the structure using various materials is determined as well as testing of the materials to check whether it conforms to the required standards or design requirements. 

Details of equipments

1. Universal testing machine (U.T.M.)
   U.T.M. is intended to test materials under various loading conditions which generate tension, compression, flexure and shear on the material. Maximum capacity of the machine is 100 tones. Some of the properties of the materials found from this machine are yield stress of steel, modulus of elasticity of steel, shear strength of steel in double shear, flexural strength of steel, wood and concrete etc.
2. Torsion testing machine
   Torsion testing machine is used to test the strength of materials in bending about its longitudinal axis thereby causing twist on the material.
3. Impact testing machine
   Determines the energy absorbed by material in impact. This is found by dropping a hammer from height in such a way that it rotates and hits the material before proceeding in the opposite direction.
4. Spring testing machine.
   This is used to determine the modulus of rigidity of the material especially, steel.
5. Fatigue testing machine
   For mild steel, there exists a limit of stress at which the material will not fail under fatigue loading. ie., the material will be subjected to cyclic compressive and tensile stresses. This machine is intended to find this limit for the stress.
6. Hardness testing machines
   There are indirect methods to determine the strength and other engineering properties of materials. Under a constant load, the diameter of indentation made on the surface of a material depends on the toughness of the material (Toughness is the ability to absorb energy). This is expressed in non-dimensional terms such as hardness number. Equipments for determining this hardness which are available in the laboratory are Brinell hardness testing  machine (maximum load which can be applied is 300 kg-f), Vicat's hardness tester and Rockwell hardness tester.
7. Torsion pendulum
   This is used to determine the modulus of elasticity of material. The underlying principle is the oscillatory motion induced on the circular disc attached to a string is a function of the modulus of rigidity of the material of the wire.
