地球自转产生的应力场

THE STRESS FIELD OF THE EARTH DUE TO ITS ROTATION

摘要:

以匀速自转时地球产生的变形做为有限弹性变形去计算,再选加地球自转角速度变化而产生的弹性变形,从而得出问题的力学解析表达式。

Abstract:

In this paper, based on the theory of finite elastic deformation, we have obtained the stress components of the crust of the Earth under uniform angular velocity. After this, infinitesimal elastic deformation theory is appied to get the additional stress due to the change of angular velocity.
