A steel component is subjected to fatigue loading : σ(maximum)= 200 MPa, σ(minimum)=0. The component has an initial crack length of 1mm. Propagation of crack is governed by: da/dN= 10-12 (ΔK)3, where, the crack length a is in metres, N ...Read more
A steel component is subjected to fatigue loading : σ(maximum)= 200 MPa, σ(minimum)=0. The component has an initial crack length of 1mm. Propagation of crack is governed by: da/dN= 10-12 (ΔK)3, where, the crack length a is in metres, N is the number of cycles and ΔK is in MPa m1/3. The crack length of (in m) after one million cycles will be _____ (answer up to three decimal places)
