By strain determination and fracture test for special compact tensile (SCT) specimen developed from standard CT specimen ,it has been proved that SCT specimens can reproduce well main characters of high strain region nearby nozzles in pressure vessels .

This paper analyzes the influences of geometric nonlinear effect on mechanics characters of high strain region in nozzles through calculating this area′s stress intensity factor and displacement by using 3 D large strain elastic plastic finite element program.
