Tensile strength:

What will be its ultimate tensile strength?

Solution

The condition for necking is 1850_Tensile strength.png = n = 0.3077

Hence using this value of1850_Tensile strength.png, the true stress at necking

2124_Tensile strength1.png= 449.35 (0.3077)0.3077

             = 449.35 × 0.696

 2124_Tensile strength1.png= 312.67 N/mm2

Hence maximum load,1155_Tensile strength2.png where, Au is the area of cross-section at Pu.

 Note

193_Tensile strength3.png

0.3077 = ln  (128.6144/ Au)

∴          128.6144 / Au  = 1.36

or         Au = 94.55 mm2

∴         1988_Tensile strength5.png

                  = 312.67 × 94.55 N

                  = 29.6 kN

The ultimate tensile strength =  Pu / A0  = 29.6 × 103 / 128.6144
