Question

Calculate the rate of crack growth when a mild steel plate is subjected to a cyclic stress with stress in tension as 500 MPa and stress in compression is 60 MPa.Consider the geometry factor as f = 1 and the plain strain fracture toughness of mild steel as 80

Answer 1

Answer:

with stress in tension as 500 MPa and stress in compression as 60 MPa. Consider the

geometric factor as f =1 and the plain strain fracture toughness of mild steel as

80 MPa.​
