Strength of Materials Laboratory

This machine is used to perform dynamic or static tests on materials such as tensile, compression, bend, creep, fatigue, DaDn, JIC, KIC. It is controlled digitally and has a furnace attached to it which can be used for tests at elevated temperatures. The maximum temperature that the furnace can provide is 1400 degree C.

This machine is used to perform tensile, compression, shear and bend test. It operates on hydraulic loading and can be controlled manually. The maximum load attainable is 200kN and maximum displacement is 200mm. It also has a load stabilizer that can be used to apply a constant load for a period of three minutes.

This is used to study the toughness or energy absorbing properties of various materials under two types of impact tests i.e. Izod and Charpy impact tests.

This tester is used to obtain twisting moment-twist relationship of a specimen and to determine shear modulus G, yield stress τy in pure shear, experimental ultimate torque.

Rockwell hardness tester is used to determine the Rockwell hardness of materials. Provisions to apply a major load of 60kgf, 100kgf and 150kgf are available in this machine. Both diamond and steel ball indenter can be fitted in this machine It directly calculates the Rockwell hardness value upon completion of the test.

To determine the brinell hardness of materials. The maximum and minimum load that can be used for testing in this machine is 3000kgf and 250kgf respectively with steps of 250kgf. Hardened steel ball indenters of 10 and 5mm diameter can be used for making indents in this machine.

This is used to determine the Vickers hardness of materials. A maximum of 50kgf and a minimum of 1kgf load can be applied for the test with a diamond indenter

This equipment is used to view and measure the principal stress components and directions of principal stresses by the photoelastic method for the plane stress condition at any given point in a photoelastic sample.

To provide experimental evidence to the elementary beam theory with the help of a cantilever beam apparatus by measuring the strains using strain gages and compare them with the theoretical results.

To study the fatigue failure of materials.

To compare the zero stress position with the theoretical position of the neutral axis in a beam by applying increasing force to it and measuring the resulting strain

To show the linearity of the strain gauges in the open end condition in a thin cylinder, to find the hoop stress and strain relationship for the cylinder material and to find the longitudinal and hoop strain relationship.

To determine the Euler buckling load experimentally and compare it to the Euler theory. Also to study the effect of end conditions on the buckling load.
