neutral axis是什么意思

网络释义

用法例句

In order to research the non-linearity structure behavior of the cracked prestressed concrete beam, some factors were considered by using Timoshenko layered beam theory, including the constitutive equation of concrete and steel, the tension stiffening affection of concrete, and the impacts of neutral axis changing on the prestressed concrete beam s mechanical performance.

为了研究预应力混凝土梁开裂后的结构非线性行为,基于Timoshenko分层梁理论,选取恰当的混凝土和钢筋的本构关系,考虑了混凝土的拉伸刚化效应和中性轴变化对预应力钢筋混凝土梁的受力、变形的影响,有效地模拟了预应力混凝土梁的开裂、屈服和失效全过程。

Based on the different moduli theory, the formula of neutral axis, normal stress, and shear stress of the structure is derived.

根据结构特点,该文给出了不同模量刚架的中性轴、正应力、剪应力计算公式以及用不同模量理论解此类结构的计算方法;对一实例进行计算分析,用编制有限元程序计算与解析解进行对比分析;最后对两种方法计算的差异进行分析并得出结论。

The determination of the neutral surface of the structure was made,and the calculating formulas of neutral axis,normal stress,shear stress and displacement were derived.

　选择处于平面复杂应力状态下横力弯曲梁,对结构进行了中性层的判定,推导出中性轴、正应力、剪应力、位移的计算公式,得到如下结论:对于复杂应力状态下的不同模量弹性弯曲梁,其中性轴位置与剪应力无关,因此用正应力作为判据而得到解析解,改进了以往用主应力判定中性点的多次循环的计算方法·　把解析解的结果与经典力学同模量理论,以及有限元数值解进行了比较,结果表明:解析解很好地考虑了拉压不同模量的效应·　还提出了对不同模量结构的计算修正以及对结构优化的思想·

The sections of beams are divided into two types based on the location of plastic neutral axis.

根据塑性中和轴的位置把梁的截面分为2类,分别给出了它们的判别条件和抗弯承载力的计算公式,以此确定构件的承载力。

In the fully plastic condition, the neutral axis does not necessarily pass through the centroid.
