变化应力 meaning in English

fluctuating stress

For instance , numerical simulations show that in discrete models made of interacting blocks carrying a continuous scalar stress variable , the average stress is about two thirds of the stress threshold for rupture
例如，数字化模拟显示，由相互作用的承载着连续梯度变化应力的地块构成的离散模型中，平均应力大约为导致破裂应力极限的三分之二。
On the basis of the important research project of the ministry of communications - the prevent and study of slope disaster in the project of beijing - zhuhai highway , the thesis developed the structure ' s design theory . in order to design more reasonable , the thesis propose the cohesion shear stress is unequal distribute at the anchorage zone . and it can be divided into two parts , the front function is uniform and the behind is exponential
为了合理的进行工程设计，本文按弹塑性理论对预应力锚索锚固段的黏结剪应力进行了分析，将锚固段划分为塑性变形区段和弹性受力区段两部分，认为锚固段黏结剪应力为非均匀分布，前段剪应力为均匀折减应力，后段剪应力为寸旨数变化应力，由此提出了相应的锚固段长度计算公式。
