    Abstract: PURPOSE: A crack retardation method of the damaged part of a plate material is provided to stop or slow down the crack growth rate by generating compressive residual stress on a crack tip. CONSTITUTION: A crack retardation method of the damaged part of a plate material comprises the following steps. A crack tip of a metal plate which includes crack is heated to prevent the crack growth on the metal plate. The heating is implemented on the position with a fixed space from the crack tip. The metal plated is quickly cooled after heating. The heating generates compressive residual stress to retard the crack growth rate.
