  • As it is difficult to obtain the accurate analytical solutions for the stress constraints of general 3d cracks , we have conducted systemically detailed researches on the out - of - plane stress constraint by finite elements ( fe ) and proposed a two - parameter description of non - through thickness 3d crack fields . several problems in damage tolerant design were also investigated based on continuum mechanics and probability theory
    三维应力约束对精确预测结构破坏不可缺少,因此,本文采用三维有限元等方法基于连续介质力学、概率论等理论,对典型三维裂纹尤其是非穿透裂纹系统深入地开展了三维应力约束理论计算、三维裂纹端部应力场描述以及结构三维损伤容限设计的研究。
  • Considering the influence of material original flaw , the thesis gave the 4 # 125t crane of no . 3 steel - making plant of maansan steel co . for example to analyze the designing and remaining life of the crane ' s girder by using damnification limits design method . the method was based on the theory of rupture dynamics and the principle of disrepair - security
    本文以马钢第三炼钢厂4 # 125t铸造起重机主梁下盖板大面积可见裂纹情况为例,考虑材料初始裂纹的影响,在断裂力学理论和破损?安全设计原则的基础上,采用损伤容限设计法来重新计算铸造起重机的设计寿命;并对正在服役的铸造起重机计算其剩余寿命,为铸造起重机的安全运行提供了较可靠的理论依据。
  • The fem model was accurate and effective by using submodel and error estimation technique that ensured the reliability of calculation and analysis . the thesis got the measure of critical flaw and designing life of the girder . in addition , the thesis calculated the remaining life of the girder while the flaw reaching 150mm
    结合有限元分析结果和损伤容限设计方法,本文计算了马钢第三炼钢厂4 # 125t铸造起重机主梁下盖板的临界裂纹尺寸,及初始裂纹为0 . 5mm时主梁的设计寿命,并估算了在裂纹尺寸达到150mm时主梁的剩余寿命。
