Tensile Tests ( Part – VI)
Factors influencing yield stress
The stress at which yield occurs is dependent on both the rate of deformation (strain rate) and, more significantly, the temperature at which the deformation occurs. Early work by Alder and Philips in 1954 found tha...

Yield Criterion
A yield criterion is an hypothesis concerning the limit of elasticity under any combination of stresses. There are two interpretations of yield criterion: one is purely mathematical in taking a statistical approach while other models attem...

Tensile Tests ( Part – III)
A DUCTILE material, like structural steel, is one which exhibits a clearly defined yield point followed by a large plastic strain, which allows the material to be bent or drawn without breaking and such material can absorb large amounts of strain ener...

Routine Tension Test of Steel
In this test the ultimate tensile strength, the yield point, the percent elongation, and the character of the fracture are determined. Sometimes the percent reduction of area is also determined. The Standard tensile-test spec...
