卸載模量 的英文怎麼說
中文拼音 [xièzǎimóliáng]
卸載模量
英文
unloading modulus-
In the simulation and analysis on culvert construction, the method of foundation - pit excavation layer by layer and step by step was used, i. e. the method that makes the surface of excavation have no stress, when the elements were excavated gradually in period of construction. at this process, the state of soil is unloading, the laws of stress field and displacement field with the depth of excavation were studied. based on the obtained stress field and displacement field after the excavation was completed, by using of the newly increased filling - elements " gravity and the grinding force, the simulation of the construction of body of the culvert and foundation - pit ' s filling layer by layer had also been done in this dissertation
用有限元法模擬分析涵洞基坑開挖時，採用分層、分步模擬開挖過程的方法，即將計算域內單元分層「挖去」 ，使開挖表面成為無應力表面的方法，分析土體在卸載狀態時的應力場和位移場隨開挖深度的變化規律；在洞體施工后，回填土體時，據開挖完成時的應力場、位移場，通過逐級增加計算域內的單元數目，施加每級新增加單元的自重荷載，利用有限元法模擬基坑及上覆土體分層填築的施工過程，這不僅反映土體處于再加載應力狀態時，填土受力及變形的一般規律，而且這種將地基? ?涵洞? ?土體作為一個統一整體進行模擬的方法，量化了三者之間的相互作用關系。On the basis of the research by former people, the work of this paper includes several aspects as follow : throughout a great deal of experiment of the mechanics performance of 2d weave c / sic composite materials laminated plate, we simulated the nonlinear relationship between a and e in the tensile course ; and we inspected the original damages and the damages evolvement ; and we made the statistic analyses of the tensile strength. some important conclusions have been given in the paper
主要有以下幾個方面：在大量二維編織c sic復合材料力學常規性能的實驗基礎上得到了拉伸實驗中卸載點和卸載模量，卸載模量和加載斜率，加載斜率和應力等之間的關系，並在此基礎上得到了模擬同種材料拉伸曲線的非線性的應力?應變關系；配合我們的實驗過程進行初始損傷和缺陷的檢測以及實驗過程中材料損傷演化過程的動態無損檢測；對我們現有的二維編織c sic復合材料拉伸強度數據進行了分佈擬合。Xiaoshan jiangdong wharf the wharf is built as a loading and unloading habour for 5000 - ton freighter, which has the capacity of handling 1500 to 2000 tons of freight annually
