SECTION B-Structural Analysis 5. A thin-walled cylindrical pressure vessel with a diameter, D = 8 m, and an operational pressure 5 MPa made from a steel with a yield strength of σys = 1250 MPa and Kic=126 MPa√m. Failure of the pressure vessel can be assumed to occur from embedded elliptical defects orientated perpendicular to the hoop stress. The largest crack found by NDT in […]
