摘　　要：文章讨论了同一材料在平面弹性中的周期焊接问题,通过引入两个全纯函数,将问题转化为周期黎曼边值问题。通过应力函数的表达式,并使用柯西型积分,研究了周期焊接问题的稳定性。This paper discusses periodic welding problem for the same material in plane elasticity. By introducing two holomerphic functions, periodic Riemann boundary value is studied; by introducing stress function and Cauchy＇s integral formula, the stability of the periodic welding problem is studied.

关 键 词：应力函数 周期焊接问题 摄动 稳定性
