采用小锥度试样，结合拉伸试验和有限元法，对氢致裂纹的起裂应力进行了测量。通过对试件上裂纹位置和深度的回归分析，预测了裂纹的起裂位置，并可直接计算出相应的起裂应力。发现了相邻裂纹应力干涉的临界相对距离，并证明了预测裂纹萌生位置上的应力不受相邻裂纹的影响。通过与传统的平行圆柱试样法的比较，验证了小锥度试样法的准确性和可靠性。
The small tapered specimen was used to measure the crack initiation stress of hydrogen-induced cracking with a combination of tensile test and finite element method. Based on the regression analysis of measured crack location and depth on the specimen, the crack initiation location was predicted and then the corresponding crack initiation stress could be directly calculated. A critical relative distance of stress interference between adjacent cracks was found, and the stress on the predicted crack initiation location was proved not influenced by its adjacent cracks. Accuracy and reliability of the small tapered specimen method were successfully demonstrated through comparison with traditional parallel-sided cylindrical specimen method.
