For static loading - brittle.

Cyclic loading - brittle and ductile.

@Amal.

Good explanation.
Vinay BEL said:   5 years ago
Agree, ductile material is right one.
Tarik said:   5 years ago
Yes, C is the right answer.
Nayyef Talib said:   5 years ago
I agree @Anuj.

The answer should be option C.

Stress concentration is more serious in the brittle material when the load is static but when it is dynamic load it is serious to both ductile as well as brittle. Since the fatigue failure normally occurs in the range below yielding point.

The answer is C because the stress concentration factor serious for both ductile and brittle material in cyclic loading.

For Static loading, its more serious for Brittle Materials, but for Cyclic loading, Stress concentrations is serious for both Brittle & Ductile.

The answer should be option C.

Stress concentration is more serious in the brittle material when the load is static but when it is dynamic load it is serious to both ductile as well as brittle.
