Bending test is an important engineering test that is conducted on timber (wood) to determine its Modulus of Elasticity, E of a given sample of wood using static bending.

In compression test, attempt is made to apply an axial load to a test specimen so that uniform stress distribution can be ensured over the critical section. In such tests the specimen is subjected to a gradually increasing (i.e. static) uniaxial load until failure occurs. The static compression tests are the most commonly made and are among the simplest of all the mechanical tests. These tests ...

The tile sample is pressed under a specified load against a grinding path, strewn evenly with an abrasive power revolving at the rate of 30±1 revolutions per minute. The wear of the tile is measured using a thickness gauge.The abrasion testing machine consists of a replaceable grinding path fitted on a disc rotating about its vertical axis. The rotating disc and the grinding path are enclosed b...

The Izod impact strength test is an ASTM standard method of determining the impact resistance of materials. A pivoting arm is raised to a specific height (constant potential energy) and then released. The arm swings down hitting a notched sample, breaking the specimen. The energy absorbed by the sample is calculated from the height the arm swings to after hitting the sample.

The Charpy impact test, also known as the Charpy V-notch test, is a high strain-rate test that involves striking a standard notched specimen with a controlled weight pendulum swung from a set height. The impact test helps measure the amount of energy absorbed by the specimen during fracture.

Torsion test on Mild steel using digital torsion Testing machine. Description about test- In torsion testing the circular bar is placed in the machine such a way that its longitudinal axis coincides with the axis of the grips and so that it remains straight during the test. Then rotate one grip at a reasonable constant speed until the test piece breaks, here the shearing stresses will develop i...
