立方准晶材料的剪切裂纹问题
Crack Problem Under Shear Loading in Cubic Quasicrystal
【摘要】 通过引入位移函数,使得立方准晶的轴对称弹性问题归结为求解一个高阶偏微分方程· 在此基础上,研究了立方准晶含有圆盘状裂纹的剪切问题,得到了此问题弹性场的精确解析解,以及应力强度因子与应变能释放率·
【Abstract】 The axisymmetric elasticity problem of cubic quasicrystal is reduced to a single higher_order partial differential equation by introducing a displacement function.Based on the work,the analytic solutions of elastic field of cubic quasicrystal with a penny_shaped crack under the shear loading are found,and the stress intensity factor and strain energy release rate are determined.
