plastic after effect 中文意思是什麼
plastic after effect
解釋
塑性後效-
But this method still exists some shortcomings such as : while adopting displacement - control analysis method how to estimate the structural displacement requirement, how to select the horizontal load mode before and after the structure yields, how to considerate the high level mode that have a large effect while it is in the later position, how to considerate the elastic - plastic response spectra correctly. these problems remain to be solved. so this method needs to improved furtherly
但該方法仍存在一些不足，如：分析時採用位移控制的方法時，如何預估結構的最大位移需求；結構屈服前後水平荷載的分佈模式如何選取；對結構影響顯著但比較靠後的高階振型如何考慮；如何正確的考慮結構的彈塑性反應譜等問題仍沒有得到很好的解決，因此該方法仍需進一步的改進。 -
Based on the idea of the measured displacement can be divided into elastic and plastic parts, elastic parameters can back analyzed by the elastic displacement, which is the measured instant after blasting excavation. the strength parameter can be got by plastic deformation, which is the measured during the period of construction loop without blasting excavation. lastly, depending on fenner formula, a new and valid evaluating criterion for tunnel stability is presented and the effect of deformation modulus, cohesion, internal friction angle and overburden can be considered
以解析理論為基礎提出一種實用而簡便的圓形洞室彈性反分析方法，且將其應用推廣到其它洞型、分步位移等不同情況；提出一種圍巖強度參數反演方法，並對其可靠性進行了初步研究； （ 4 ）依據芬納公式提出了能夠考慮圍巖變形模量、強度參數、埋深等主要因素的、新的、有效的圍巖穩定性評判方法。 -
Due to the overproduction, the industrial benefit is very low. after the chemical industrial policy took effect, the plastic frame industry achieved the rapid growth
由於生產能力的大量過剩，行業整體的效益低下。在化學產業政策的推動下，出現了90年代塑料門窗前所未有的超常發展。 -
Abstract : in one sintering plant, its no. 1 wagon tipper ' s track sur face occurred corrosive pitting and stacking only after short application, and th is effect the normal production seriously. in order to diagnose the plastic defor mation of the track surface, we made test and fem analysis to it, found the re ason of failure, and put out improving measure
文摘:某燒結廠1號翻車機在使用較短時間后，導軌表面出現點蝕和堆邊現象，嚴重影響正常生產.針對這一問題，對導軌表面塑性變形進行了實測和有限元分析，從而找出了故障原因並提出了改進措施 -
