  1. Most existing constitutive models do not take into account the interactions between different phases of pearlitic steel and cannot illustrate why such kind of materials has excerllent mechanical properties. it is, therefore, necessary to develop a new method, which can describe the macroscopic behavior, damage and failure of the materials and their micro structural dependence. in this paper, based on a non - classical theory of plasticity and the continuum damage mechanics, a damage evolution based on an ellipsoidal void model for mixed hardening materials is obtained

  3. In order to study the influence of evolvement of permeation character induced by mesoscopic structural characteristics on macroscopic mechanical behavior and fracture mechanism, a nonlinear constitutive equations describing the relationship between damage of rock and seepage is proposed based on mesoscopic damage mechanics and biot seepage mechanics theory and coupling system of flow & solid in rock failure process analysis, f - rfpa2d, is developed to simulate the variation of permeability as well as coupling mechanism between seepage and stress during the initiation, propagation and coalescence of cracks in rock. this study also extends the research field of original rfpa2d

    為了分析細觀結構特性變化引起滲透性演化對宏觀力學行為的影響,並進行滲流應力耦合作用下巖石破裂機制的研究,本文基於細觀損傷力學和biot經典滲流力學,建立了巖體損傷非線性本構方程和滲透率關系模型,開發出巖石破裂過程滲流-應力耦合分析系統( couplingsystemofflow & solidinrockfailureprocessanalysis簡稱f - rfpa2d ) ,拓寬了原有程序rfpa2d的研究領域。
  4. Presents the investigation of the heat conduction behavior, internal thermal stress field of specimen under thermal shock and microscopic damage and failure of the tungsten based composites by combination of macroscopic and microscopic analyses and integration of material science and mechanics ; describes a microscopic mechanical model based on the microstructure of components with macroscopic stress applied to the microscopic model as that of maximum principal stress at the center, and the fringe of the specimen, and the microscopic stress fields obtained through calculation by the finite element method, and concludes from test results that the maximum principal stress is first generated inside the test coupon, and a failure will be first initiated in the inclusion if the material fails at this time ; the maximum principal stress moves to the edge of the test coupon after the test coupon is heated for a period of time, and the failure will first be initiated in the base if the material fails at this time

    從材料設計的思想出發,採用宏觀與微觀、材料科學與力學相結合的方法,對鎢基復合材料的熱傳導行為、材料在熱沖擊載荷下的內部熱應力場及材料細觀結構的破壞行為進行了詳細的理論研究.根據鎢基復合材料的細觀組織結構建立了材料細觀模型.在宏觀分析的基礎上,分析了材料微結構內部的破壞行為.分別取試件心部與邊緣主應力值最大點的應力狀態,施加在所建立的模型上,用有限元方法計算了模型內部的彈性應力場.結果表明:試件主應力最大值首先產生在試件內部,此時,如果材料發生破壞將先從夾雜中開始;加熱一段時間后試件中的最大主應力值轉移到試件邊緣,此時材料發生破壞將先從基體中開始
  5. At the macroscopic scale, it can be considered that we are in presence of a damage accumulation via matrix microcracking coupled with interfacial sliding phenomenon which may be settled according to a slow crack growth mechanism

    在宏觀層次上,可以把通過基體微裂紋和界面滑動所形成的損傷積累看作是一種裂紋的緩慢生長過程。
  6. The worsening of credit surroundings has produced much damage to social economic life, such as : market which is short of credit affects the social investment and consume and destroys the normal management of enterprise, enlarges costs of enterprise management, makes the macroscopic control tool useless and enterprise are not willing to invest, banks are n ' t willing to make loans, and it ' s difficult for the government to start investment and enlarge domestic demand, even it directly damages the basic of social legal system, and all types of economic principal parts are difficult to form the legal frame in the basis of construction. many enterprises compete in all kinds of improper ways and ruin the social atmosphere and decline the morals level

    信用環境惡化已對社會經濟生活產生諸多危害:市場缺乏信用嚴重影響社會的投資和消費,破壞企業的正常經營,加大企業經營成本;政府的宏觀調控政策和工具難以發揮作用,企業不敢投資,銀行不敢放貸,使政府啟動投資、擴大內需政策的效用大打折扣;信用惡化還直接破壞社會的法制基礎,各類經濟主體在信用關系中難以形成以合同為基礎的法律框架,許多企業以種種不正當的手段展開競爭,是造成社會風氣敗壞,道德水平滑坡。
