| 摘 要： | 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。

| Abstract: | 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. |
