對于蠕變裂紋擴展的分析研究還是處于初期階段，還有許多事情有待于認識和完成。Against the background of the microstructural evolution of three dimensional braiding c / sic composites, used such analytical methods as lm, sem and tem, it is studied that the matrix cracks propagate in the composites with different interphase thickness under three - point - bend testing, as well as under the creep testing. the main conclusions are as follows : 1
本文以三維編織c sic復合材料微結構演化為背景，採用光學顯微鏡（ lm ） 、掃描電鏡（ sem ）和透射電鏡（ tem ）等分析手段，研究了不同界面相厚度的復合材料在三點彎曲測試中基體裂紋的擴展規律，以及基體裂紋擴展對蠕變過程的影響。( 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 ）在用巖石中大小、方位和位置均為隨機分佈的裂紋定義損傷變量基礎上，利用線粘彈性斷裂力學原理對考慮裂紋內水壓的巖石的損傷蠕變問題進行了建模和分析。3. the two stages of primary creep and steady - state creep of 3d c / sic correspond to the gradual saturation of matrix crack and the opening of these cracks respectively. the transverse crack is the main contributor to the macroscopic creep strain of 3d c / sic, and its opening is controlled by the creep temperature
（ 3 ） 3dc sic復合材料的減速蠕變階段和穩態蠕變階段分別對應著基體裂紋趨于飽和和逐漸張開這兩個過程；橫向基體裂紋是3dc sic復合材料宏觀蠕變應變的主要貢獻者，溫度是影響橫向裂紋張開速度的一個重要因素。Test methods for conducting creep, creep - rupture, and stress - rupture tests of metallic materials
金屬材料的傳導蠕變蠕變裂紋和應力裂紋測試方法Fatigue experiments were performed to obtain the fatigue lifetime under the different loading. the parameters for law of the fatigue crack growth were obtained by crack growth experiments. in order to study the fatigue characteristics at high temperature, creep tests were also done
本文對多種典型焊接試件開展了諸多的試驗研究工作：進行單軸靜載拉伸試驗以確定構件的強度；進行疲勞壽命試驗以測得疲勞壽命曲線；進行疲勞裂紋擴展試驗以獲得試件的疲勞裂紋擴展規律paris公式；進行蠕變試驗以考察焊接試件疲勞持久特性；進行剩餘壽命試驗以獲得試件的剩餘壽命。Abstract : based on the hypotheses of three - piece straightening curve. it isverified that the method for using little deformation condition was true with accurate solution of three - piece straightening curve. the mechanics behavior of slab was analyzed in regard to the creep properties of high temperature slab. the results show that the strain, the strain velocity and the stress varied so smoothly that the inner crack was prevented. technical renovation is carried on by adjusting the displacement of rolls and by using the accurate solution of three - piece straightening curve
文摘:基於三段矯直曲線應變速率的假設，通過計算三段矯直曲線的精確解，驗證了使用小變形條件的正確性;考慮高溫鑄坯蠕變性能，對鑄坯的力學行為進行了分析，得出了使用三段矯直曲線方法，鑄坯應變速率、應力及應變在矯直區內變化較為平緩，可有效避免鑄坯內裂紋的形成;使用本文三段矯直曲線精確解，調整輥列位置，可進行連鑄機的在線技術改造。Once matrix microcracking has reached the saturation state, microcracking opening due to a time - dependent mechanism, which is encountered at the fiber / matrix interface, has been evidenced
一旦基體開裂達到一種飽和狀態，裂紋在界面處被止住，然後裂紋會隨時間在蠕變實驗中緩慢地張開。分享友人
