Author thinks that the direction of the maximum plastic distortion along a constant radius around the crack tip may be considered as the direction of shear - mode fracture ( named pmax - criterion ) and the load when located shear band prongs the ligament in the front of crack tip is regarded as the limited load of shear - mode fracture. ( 3 ) the fad ( fracture assessment diagram ) of titled crack is proposed based on achievements of mesomechanics about i - ii complex ductile fracture of metal, and the titled crack is classified two kinds : void - mode fracture is assessed by fracture assessment curve, and shear - mode fracture by limited load. ( 4 ) using a fe program based on plantle - ressue theory to calculate some mesomechanical parameters, a flange joint structure of a high pressure vessel ( design pressure 31. 4mpa and the thickness of the hemispherical head is half of that of shell. ) is analyzed to determine whether the structure under operation pressure is safe or not, forecast the mode of potential invalidation and argue for the rationality of design of the structure
試件的整體斷裂為剪切型,但在試件芯部裂尖鈍化區中部出現了韌窩型啟裂並有一定的擴展,說明局部較高的應力三軸度也會使韌窩型機制得以發展,但是不改變試件整體的剪切型斷裂模式;對韌性斷裂的剪切模式的細觀機理做了一定的探討,並且提出了含裂紋構件剪切型斷裂的宏觀判據:認為裂紋前方的集中剪切帶中與裂紋尖端等半徑處最大有效塑性應變出現的方向可以作為裂紋剪切斷裂的方向(可簡稱為_ ( pmax )準則) ,集中剪切滑移帶貫穿裂紋前方承載韌帶時的載荷可以作為極限載荷;本文運用金屬韌性斷裂細觀力學在一復合型韌性斷裂方面的研究成果,採用失效評定圖的形式,提出了傾斜裂紋的安全性評定方法的基本框架。Lastly, aiming at the poor results which all current algorithms do for directional textures, and cannot synthesis texture directly, aiming at the particularity of this kind of textures, we bring forward the conceptions of non frontal parallel textures and frontal parallel textures. by analyzing texture ' s direction through fourier spectrum, we introduce the conception of main direction, and solve the approximation value of texture ' s main direction by discrete approximated approach. by this way, we can synthesis indirectly simple structural non frontal parallel textures
最後針對現有演算法對帶有方向的紋理合成效果差,無法直接合成紋理圖像的難點,本論文首先提出了非正平行紋理與正平行紋理的概念,分析了它們之間的內在聯系,引入了兩個角度參數來描述紋理的朝向,採用傅立葉頻譜法分析紋理的方向特性,並提出了紋理主方向的概念,本論文引入離散逼近的方法來求解出紋理主方向的近似值,這樣我們就能用一種間接的方法合成簡單的結構性非正平行紋理。Such integra ting feature vector is used for building k dim e nsion gaussian m odel, whose param e ters are estim ated by an expectation - m a xi m i zation ( em ) algorithm, and then the resulting block - cluster m e mberships provide a segm entation of th e im age. after segm ented, a m e thod of param e ter - trimm e d average for describing re gion is proposed, of which the param e ter is decided by area and position of region dire ctly. the sim ilarity m easure between two im ages is defined by integrating properties of all regions in the im age
文中先將圖像分成4 4小塊,各塊的顏色、紋理、位置特徵構成8維的特徵空間;在該空間中對得到的8維特徵矢量建立一個k維高斯模型,應用期望最大em演算法估計模型參數,產生的塊特徵-聚類隸屬度函數實現對圖像的分割;為減小分割演算法不確定性對檢索效果的不良影響,對得到的區域採用參數均衡平均特徵表示,其中參數的確定直接與區域的面積、位置有關。
