摘要: 由塑性失稳理论导出了无缺陷钢瓶爆破压力和容积膨胀率的表达式,由塑性极限载荷理论导出了缺陷钢瓶爆破压力的表达式,由不同断裂准则比较确定了退火不充分钢瓶从低塑性断裂向脆性断裂过渡的临界损伤度。由理论和试验研究所确定的钢瓶损伤容限已经采用在国家标准《液化石油气钢瓶定期检验与评定》中。

Abstract: A fracture criterion based on plastic limit lend theory was propound for characterizing the fracture behavior of liquefied petroleum gas cylinder with or without defects. The damage tolerance derived from this criterion was admired in Chinese Standard "Periodic Inspection and Evolution of Liquefied Petroleum Gas Cylinder".
