双周期刚性线纵向剪切问题的应力奇异因子

STRESS SINGULARITY FACTOR OF DOUBLE PERIOD RIGID LINES UNDER LONGITUDINAL SHEAR

研究了双周期刚性线的纵向剪切问题 .利用椭圆函数的保角变换、Riemann Schwarz对称原理和奇点分析等技术 ,得到了全场应力及应力奇异因子的精确解 ,分析了刚性线夹杂横向和纵向间距对应力奇异因子的影响 .

Longitudinal shear problem of the double rigid lines is dealt with. By using of conformal mapping of elliptical function the symmetric principle of Riemann-Schwarz and singular point ana-lysis techniques, the stress field and stress singularity factor are derived. The effects of transverse and longitudinal spacings between rigid lines on stress singularity factor are analyzed. From the limiting case of that obtained, some existing result can be arrived at.
