With analysis of the control variables of the creep deformation, the creep speed and the creep acceleration, the modified Xiyuan model can be used to better describe the three stages of rock sample creep, especially the non_linear accelerating creep stage. 通过对蠕变、蠕变速度、蠕变加速度的控制变量渐变分析表明,改进的西原模型能够较好地描述岩石三阶段蠕变变形,尤其是非线性加速阶段蠕变变形。
The new equation correctly reflects such a fact as that the creep damage starts or appears at the end of the second stage and results in the accelerating creep and failure. 造成软岩蠕变加速阶段出现的原因是损伤起始于或明显显现于蠕变第二阶段之末。
Introduction to time? temperature superposition ( TTS) method for accelerating creep testing procedure of geosynthetics 加速土工合成材料蠕变试验的时温叠加法简介
The results show that the creep deformation of this alloy is mainly controlled by the creep accelerating stage, or the creep deformation get to its stable stage quickly and then get to the third stage instantaneously. 结果显示,合金很快达到稳态蠕变阶段,随后马上进入蠕变第三阶段,即蠕变过程主要由加速蠕变控制。
Conclusions Tissue-engineering bone can repair bone defect, accelerating healing and without "creep substitution", which is a good option in repair of critical segmental bone defects. 结论组织工程骨能加速骨缺损愈合的速度,其修复过程可超越爬行替代阶段;
The results show that, the new constitutive equation can effectively describe the mechanics characteristics of three creep stages of the decaying, stable and accelerating creep of soft creep; 结果表明:该方程能有效地描述软岩蠕变过程中衰减蠕变、稳定蠕变和加速蠕变等三个阶段的力学特性;
As the stress increases so that it can overcome the rubbing resistance, the accelerating creep failure of the structural surface will happen suddenly. 当外界应力水平增加到足以克服摩擦阻滞作用时,蠕变加速破坏便会直接突发。
The distributions of temperature, stress, strain, strain rate, displacement and viscous damping coefficient within ductile shear zone at different time intervals are distinguished in the cases of accelerating creep age and strain softening. 并对加速蠕变和应变软化两种情况,给出了不同时刻韧性剪切带内的温度、应力、应变、应变率、位移和粘滞系数的分布特征,描述了岩石递进变形的规律。
On the method of accelerating high-temperature creep test by an elevation of temperature 关于用提高温度法缩短高温蠕变试验的时间
Non-decay creep characteristics are presented in preloading-unloading-secondary loading tests for the soil with low water contents and high compression pressures. Moreover, the bigger the pre-loads, the more obvious the accelerating non-decay creep would be. 在预压-卸载-再加载的试验中,土体蠕变曲线在低含水率和高应力作用下呈非衰减蠕变,且预压压力越大非衰减加速蠕变现象越明显。
