非均匀切向荷载下弹性半空间二阶效应的实例计算

The Illustration Calculations of Second Order Effects in Elastic Half-Space Acted upon By A Non-Uniform Shear Load

继文[1]，本文详细讨论了一个实例，对二阶弹性材料在Z方向的位移和应力作了数值计算，我们发现，二阶效应使Z方向位移减小而使应力trz的值在荷载作用圆内减小而在圆外却增加。

This paper is a continuation of [1]. An example is discussed in detail to illustrate the second order effects. Numerical calculations for the second order elastic material for the 2-direction displacement and the stress trz are carsied out. It is found that the second order effect is to reduce z-direction displacement and to decrease trz inside the circle but to increase its value outside the circle.
