切线弹性模量 meaning in English
tangent modulus of elasticity
Examples
- The conclusions have been deduced from the detailed analysis of a set of experimental results as below : 1 ) the formula of tangent young ' s modulus et has been established during the unloading process ; 2 ) the shearing features of the samples are similar to undrained test even though there are draining paths so the possion ratio of the sample is about 0 . 5 ; 3 ) unloading paths have little effects on the shearing strength parameters
通过对试验结果的分析得到： 1 )任一时刻土体的切线弹性模量公式； 2 )卸载情况下尽管存在排水通道，但试样仍基本上表现为不排水的性状，按广义虎克定律得到的泊松比在0 . 5附近； 3 )卸荷应力路径对土体的强度参数影响不大。 - To meet the need of settlement calculation with fem when absence of laboratory triaxial test data in common road engineering , methods of determining the five parameters included in tangential elastic module through soil routine tests and the related emendation coefficient are given . at the same time , one approximately substituted formula for tangential poisson ratio is also developed , which is suitable for both sandy soil and cohesive soil .
