The Geometry Influence on Integrity Thresholds for a Cracked Cylinder
Апстракт
By applying the EPRI engineering approach, threshold values of pressure for internally pressurized axially cracked long cylinder are calculated. The JR curve and the crack driving force J are approximated by polynomials in the amount of crack growth a - a0 and in crack length (height) a respectively. It is shown the influence of cylinder geometry on internal pressure Pi corresponding to the onset of crack propagation as well on internal pressure Pf for system instability. The apparent material toughness and the relative change of pressure Pi for different wall thicknesses increase with the stable crack growth. It is shown that the relative stable crack growth is greater than the value allowed by the ASTM E-399.
