| Abstract: | In allusion to the instantaneous characteristic of the shock, the question that thick wall cylinder gets thermal shock treatment is investigated. Based on temperature field solution obtained by Laplace transform, thermal stress response of cylinder is found. The changes of thermal stress with time,and with cylinder radius ratio are discussed. It provides a theoretical reference to study on the decrease in the fatigue damage of the reactor under thermal punch. |
