The steel has yield strength of 550 MPa and a fracture toughness of 40 MPa m^1/2.What will be the limiting design stress if the maximum tolerable crack is 3.0 mm in length and no plastic deformation is permitted?
2. Please estimate the number of cycles to failure of a steel specimen under tensile fatigue loading with the following parameters. The R ratio is 3, mean stress 200 MPa, yield strength 450 MPa, ultimate tensile strength 560 MPa, Young’s modulus 200 GPa, KIC = 140 MPa . Assume the initial crack length is 0.1 mm.
A nondestructive testing program for a component made of 1040 steel can ensure that no flaws greater than 1 mm will exist. Will this inspection program be effective in preventing fast fracture?
The steel of interest has a fracture toughness of Klc =120 MPa √m, a tensile modulus of E=207 GPa, a yield strength = 290 MPa, and an ultimate tensile strength of 520 MPa.
