Linear viscoelasticity stability analysis of bluff rock slope 随机连续杆纵向振动系统的频率可靠性分析
( 7 ) basing on defining damage variable with flaws in rock , this paper uses linear viscoelasticity fracture mechanics to set up a damage reep model and analyses the model ( 7 )在用岩石中大小、方位和位置均为随机分布的裂纹定义损伤变量基础上,利用线粘弹性断裂力学原理对考虑裂纹内水压的岩石的损伤蠕变问题进行了建模和分析。
With engineering polymer - pmma taken as the main researched object and viscoelastic failure considered as the theory basis , the non - linear viscoelasticity and crazing damage phenomena under creep condition in macromolecule material were researched by means of experiment 本文以工程高聚物pmma为主要研究对象,以粘弹性破坏理论为基础,以实验为手段,对高分子材料蠕变条件下的非线性粘弹性性能及其银纹损伤现象进行了初步探讨。
From the hypothesis of linear viscoelasticity , we predicted the time of life of the three specimens with edge crack which fractured in out experiment at last in view of energy releasing . however , we found that the predicted values were on the low side obviously , so we analyzed the reason of being non - linear . on this basis , we modified the method 本文的第四章从线粘弹性假设出发,从能量释放率的角度对实验中最终断裂的三今含边裂纹的试件的寿命进行了预测,并与实验结果进行了对比,发现预测值明显偏低,分析了产生非线性的原因,进行了非线性修正。
At present , many important development on the studies of viscoelastic theory have been made by the efforts of scholars home and abroad , linear viscoelasticity theory has sufficiently developed , while nonlinear viscoelastic theory is still under developed by the reason of difficulties in experiment and mathematics 目前,国内外学者在粘弹性理论研究领域取得了许多重要的研究进展,线粘弹性理论已发展得较为完善,非线性粘弹性理论由于实验和数学上存在的困难尚处于不断的发展和完善之中。
