摘 要:本文应用复变函数论方法讨论各向同性弹性平面的周期接触问题,但使用的方法不同于文[3]。这里,是将该类问题化为我们自己解决的,关于半平面的Riemann-Hilbert边值问题。可以认为本文结果是著作[1]、[2]中有关结果在周期情况的推广。
Abstract: In this paper, it is proposed to investingate some problems of the periodic contact of elastic theory for the isotropic plane, in which a series of rigid bodies with a period of aπ is pressed to elastic half plane, when the force of friction exists. Introducing both functions expressed by integrals with Hilbert kernetW1(z)=u1-iv1=∫L0(σy)y=0 ctg (t-z)/g atW2(z)=U2-iv2=∫L0(τy)y=0 ctg (t-z)/g atWe differ from [3] to reduce these problems to the periodic Riemann Hilberi boudary problems and work out some solutions.This paper is principally a generalization of L. A. Galin’s method and result in periodic case.
