22.314/1.56/2.084/13.14 Fall 2006 Problem Set III Due 10/05/06 1. For the same vessel described in Problem II-2, find out the maximum allowable pressure of the coolant so as not to cause elastic failure under expected static loading and fatigue conditions. State the criterion you wish to apply before proceeding to numerical evaluation. • Yield stress = 320 MPa, Ultimate tensile stress = 500 MPa. • S-N curves for both high cycle fatigue and low cycle fatigue are attached. • Expected

Unformatted text preview: • Expected number of cycles between cold and hot zero power conditions = 500. • Expected number of cycles between hot-zero power and hot-full power conditions = 10 5 • Temperature profile is distributed parabolically at hot-full power conditions: 1 T = T out − Δ T (1 − 2 z/t ) 2 4 Where T out is the outside wall temperature. Δ T = -50 K is the temperature difference between inside and outside wall. 1±...
