Abstract:
Weight funct ion is approached to st ress intensity facto rs for half-ellipitical surface cracks in the temperature st ress. T he weight funct io n fo rmula are wo rked o ut and can be used for all kinds of materials, temperatur es, cracks and different thick walled shells to compute the str ess intensity factors. At the same t ime, the rule of the st ress intensity factors in the temperature st ress of thick w al l shells w ith the change of cr ack depths is obtained. T he rule is of some reference value to the desig n and engineering o f the thick w all shells.
