论文采用Bak准晶弹性动力学模型研究了十次对称二维准晶材料的位错动力学问题.将Stroh公式推广到了准晶材料动力学问题的研究中,给出了位移和应力一般解的表达式.讨论了位错移动速度、声子场和相位子场耦合弹性常数R对声子场、相位子场位移和应力的影响.“,”Quasicrystals have widespread application values and prospects because of their excellent physical and mechanical properties.In this work,based on Bak's dynamic model of quasicrystals,the moving straight dislocations in decagonal quasicrystals are investigated in detail.The closed-form expressions for elastic displacement and stress fields are obtained by extending the Stroh formalism.Effects of the moving velocity of dislocation and the phonon-phason coupling elastic constant on the hoop displacements and stresses are discussed.The results show that the greater the moving velocity of dislocation is,the more significantly the displacements and stresses in the phonon and phason field are affected.Finally,the dynamic physical characteristics of dislocations are revealed,and the wave behavior is checked in phonon and phason fields.
