摘　　要：通过对由标准ＣＴ试样发展而来的异形紧凑拉伸（ＳＣＴ）试样的应变测试和断裂试验，证明ＳＣＴ试样能够很好地再现压力容器接管等高应变梯度区的主要特征。其试验结果与实物容器实测结果非常接近，并给出了推荐的高应变区裂纹张开位移（ＣＯＤ）估算式。The strange compact tension(SCT)samples were proved to show the major characteristics in the high strain gradients of pressure vessels once more through the strain test and the failure test of the SCT samples developed from the standard compact tension(CT).The test result was almost in agreement with the measured result,and the recommended calculations of the crack opening displacement (COD)in the high strain zones were given.
