Calculation of Stress Intensity Factors K and K of Grittith Cracks in the Orthotropic Plate by the Application of Superposition Principle and Symmetry—skewsymmetry Principle

  • 摘要: 近二、三十年来,随着空间技术、造船、航空、导弹和原子弹等尖端技术的迅猛发展,对材料的比强度、比刚度、冲击韧性、疲劳寿命和耐高温的性能提出愈来愈苛刻的要求,于是广泛地采用由各种合成材料制成的正交各向异性板。当然有必要研究这种构件中的裂纹的应力强度因子问题。

     

    Abstract: This paper gives the proof that the crack stress intensity factors in the orthotropic elasic plate can be calculated by using the superposition principle, and illustrates the application of symmetry-skewsymmetry principle to the Griffith crack-tip stress intensity factors. K and K of the Griffith Cracks in the orthotropic plate for more than twenty loading conditions are calculated by the application of these two principles, and their general application formulae are also tabulated.
