3 Consider two objects made of different isotropic materials

3. Consider two objects made of different isotropic materials (Aluminium and Steel) but with the same geometry, loads and boundary conditions. Which of the materials would have a higher stress and why?

Solution

>> According to Hooke\'s Law,

Stress = Strain*Young\'s Modulus

>> Now, as, load, geometry and boundary conditions, all are same.

So, Strain will be same ....

>> Now, as Young\'s Modulus of Steel is more than that of Aluminum

So, Stress Generation in Steel will be more than that in Aluminium .
