unloading modulus
解釋
卸載模量-
Abstract : the paper makes cliscussion on the problem of how to select the following computing indices : modulus, static earthpressre coefficient, strength from the excavation unloading projects computations. also it gives a large amount of data, examples and proofs
文摘:該文對開挖卸荷工程計算中所得到的模量、靜止土壓力系數、強度等計算指標的選取問題進行探討，並給出了大量的數據例證。 -
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
通過對試驗結果的分析得到： 1 ）任一時刻土體的切線彈性模量公式； 2 ）卸載情況下盡管存在排水通道，但試樣仍基本上表現為不排水的性狀，按廣義虎克定律得到的泊松比在0 . 5附近； 3 ）卸荷應力路徑對土體的強度參數影響不大。 -
Damage develops fast after that period. and a nonlinear formula with parameter of unloading modulus and residual strain was brought out to describe damage development in tensile test. it is also found that mechanical properties of c fiber are much less than those of t300 fiber bundles
另外，通過進一步的分析發現三維編織c sic復合材料中纖維束的就位性能遠遠低於其摘要原位性能，這正是c / sic復合材料的拉伸性能遠低於t300 / qy9512復合材料的主要原因。
