| Abstract: | Through theoretical analysis and mathematical deduction basing on comogan maximum circuferential stress theory, the trigonometric expression ofⅠ-Ⅱcompound crack initical angle and practical answer of circumferece fracture criterion are reached. It is of vital practical meanning to have defeat safty evaluation and life-count about cracks,which often appear in on using pressure-vessels and boilers. |
