Stress concentration in a machine component of a ductile

Home » Machine Design » Machine Design Miscellaneous » Question

Stress concentration in a machine component of a ductile material is not so harmful as it is in a brittle material because

1. in ductile material local yielding may distribute stress concentration
2. ductile material has larger young's material
3. Poisson's ratio is larger in ductile materials
4. Modulus of rigidity is larger in ductile materials

Correct Option: A

Local yielding reduces stress concentration effect.
