摘要超声弹性成像通常只能得到组织在外部压缩作用下的纵向应变分布。
Commonly, ultrasound elastography can only obtain the axial strain distribution of tissues with an external compression.
并得到纵向预应力钢筋的准确模拟对结构纵向应变计算精度影响较大的结论。
It is concluded that calculation results of longitudinal temperature strain are limited by the accuracy of numerical simulation of longitudinal prestressed reinforcement.
从加载之初直到大约0.8倍的极限承载力，试件纵向应变沿截面高度的分布基本符合平截面假定。
From 0 load till about 0.8 times the ultimate load bearing capacity, the steel tube longitudinal strain distribution along the depth of cross-section obeys the plain section assumption.
