elastic cross-section

基本解释

In the elastic region of the cross-section, the stress distribution varies linearly from the neutral axis to the beginning of the yielded area.
在界面的弹性变形区域的应力分布呈直线型，这种线性分布从截面中性轴开始到其屈服区域结束。
The pile is assumed to be vertical, elastic and of uniform cross-section, and the soil is considered as a linear viscoelastic layer with viscous damping.
假定桩为竖直、弹性、等截面体，土为线性黏弹性体，其材料阻尼为黏性阻尼。
There are many long and elastic round cross-section rod structures in quayside container crane, whose frequency are so low that it is easy to arouse crosswind resonance.
岸边起重机结构中有许多长的弹性圆截面杆件，自振频率比较低，很容易发生横风共振。
