Continuum damage mechanics
連續介質損傷力學The theory of continuum damage mechanics and the basic principle about neural network are introduced
主要對連續介質損傷力學和人工神經網路的基本原理進行了論述。Abstract : with the basic concept of damage mechanics and based on the fatigue damage equation of concrete materials, the multistage fatigue damage process of concrete materials is deeply and theoretically analyzed. accordingly the pathway of multistage fatigue damage with the characteristics of independence and continuance is provided, and the non - linearity multistage fatigue damage equation of concrete materials is inferred. the equation clearly reflects that the loading sequence has an effect on the fatigue accumulating life expectancy ; with the use of this equation the effect of overloading on the material life expectancy is analyzed
文摘:利用損傷力學的基本概念,在砼材料疲勞損傷方程的基礎上,對砼材料的多級疲勞損傷過程進行了深入的理論分析,給出了具有獨立性和連續性的多級疲勞損傷路徑,推導出了砼材料的非線性多級疲勞損傷方程,方程明確的反映了加載次序對疲勞累積壽命的影響;利用此方程,筆者分析了超載對材料使用壽命的影響By introducing damage tensor and net stress, this study has analyzed the mechanical properties of rock mass structural plane, hi this way, the rock mass question is macroscopically transformed into one of continuous medium mechanics, hi the light of the engineering reality in chengchao iron mine, the damage tensor of the area under research has been obtained on the basis of engineering geological survey
通過引入損傷張量和凈應力來分析巖體結構面的力學特性,從宏觀上將巖體納入連續介質力學的范疇來處理。結合程潮鐵礦實際,在工程地質調查的基礎上,求得研究區域的損傷張量。As it is difficult to obtain the accurate analytical solutions for the stress constraints of general 3d cracks, we have conducted systemically detailed researches on the out - of - plane stress constraint by finite elements ( fe ) and proposed a two - parameter description of non - through thickness 3d crack fields. several problems in damage tolerant design were also investigated based on continuum mechanics and probability theory
三維應力約束對精確預測結構破壞不可缺少,因此,本文採用三維有限元等方法基於連續介質力學、概率論等理論,對典型三維裂紋尤其是非穿透裂紋系統深入地開展了三維應力約束理論計算、三維裂紋端部應力場描述以及結構三維損傷容限設計的研究。As we all know that damage constitutional law of concrete is fit for solving mass little cracks situation, that fracture mechanics model is fit for solving only a few cracks situation, that separate crack model is only fit for dealing with those cracks whose locations is known firstly. but these situations do n ' t reflect the crack characteristic of the steel liner - reinforced concrete penstocks of the three gorges. so, this paper adopts the smear crack model to simulate crack
基於損傷力學模型更適合解決成群微裂縫問題,斷裂力學模型更適合解決少數裂縫情形,離散裂縫模式只能解決裂縫位置預先知曉的情形,這些都不符合三峽水電站鋼襯鋼筋混凝土引水壓力管道的裂縫特點,為此本文採用彌漫裂縫模式來進行裂縫的數值模擬,該裂縫模式能解決裂縫位置預先不知曉的情形,且能連續分析而無須重新劃分網格。Derived from the elements of the continuum mechanics, the applied fatigue damage mechanics theory system of material is analyzed, and the corresponding rule of cumulative fatigue damage is built up. combined with the applied theory of fatigue damage, a damage mechanics model for high cycle fatigue is deduced
