At the same time we study, analysis and discuss the action that non - linearity - stickiness - springiness and crazing damage of the pmma sample under creep though making us of the knowledge about the high molecule physics the damage theory of material of rheology of bodies with defects. through the study and theory analysis of single - axes stretching experiment in pmma sample under creep, take the surface crazing damage density of pmma sample as an variable, to look for a commonly rule that the crazing damage of pmma, and to offer a feasible damage model for the sake of study that of pmma ' s remoteness damage
同時運用高分子物理、含缺陷流變性物體的材料破壞理論等知識，對無孔洞pmma試件和有孔洞pmma試件蠕變條件下非線性粘彈性行為及其銀紋損傷現象進行了研究、分析與探討，通過對蠕變條件下的pmma試件的單軸拉伸實驗研究和理論分析，以pmma試件的銀紋損傷面密度值為損傷變量，來嘗試尋求pmma銀紋損傷的一般規律，為研究pmma的細觀損傷提供了一種可行的損傷模型。 -
Higher temperature can make paint ' s surface crazing and bubbling ; while lower can cause it difficult to solidify and appear flowing phenomenon
溫度過高會導致漆膜開裂、起泡；溫度過低使漆膜不易固化，出現流掛現象。 -
With the disposal of the image, we get a changing rule that the change of the sample of pmma ' s surface crazing damage density follow the change of time and stress
經圖像處理，得到了在不同應力水平下、不同基溫下， pmma試件紋損傷面密度隨時間的變化規律。具體地， 1 -
Because of the different material property of the piles and soil, shear stress is produced on the contact surface between piles and soil, which may cause slide and crazing of the soil mass under workload. in order to reflect the mechanical character precisely on the contact surface, a new kind of element, plane - plane contact element is introduced. the principle of the process is presented in detail and the finite element model is established with the consideration of the soil ' s elastoplastic constitutive relation
由於樁體結構的材料性能與周圍土層性質相差較大，在荷載作用下有可能在其接觸面上產生較大的剪應力從而導致錯動或開裂，為了充分反映樁土接觸面上的受力及變形特徵，考慮樁土之間的共同作用，在樁土接觸面處設置面面接觸單元，將採用接觸單元和不採用接觸單元兩種演算法的計算結果與模型試驗結果進行比較，驗證了本文接觸界面處理的合理性。 -
And collecting the image of the damage instance in the sample of pmma in real time on line, we get the surface crazing damage density under different time and different stress passing the image dispose of a software, and giving out a changing rule that the change of the sample of pmma ' s surface crazing damage density follow the change of time and stress
對pmma試件銀紋損傷情況進行在線實時的圖像採集，經圖像處理軟體的分析，得到了pmma試件在不同時間和不同應力水平下的銀紋損傷面密度，並給出了pmma試件銀紋損傷面密度隨時間和應力的變化而變化的規律。 -
The pmma ' s craze damage is observed on line in different temperature and invariable load, which show that the change pricks up with the increase of time and temperature. with the disposal of the image, we get a changing rule that the change of the sample of pmma ' s surface crazing damage density follow the change of time and stress. then the data from experiment is to match in non - linearity, pmma ' s density of crazing damage changing with time and stress is available
對pmma在恆定荷載作用下，不同基溫下的pmma銀紋損傷進行了實時在線觀測，結果表明： pmma試件的銀紋隨持荷時間增加，而且隨著溫度的升高，可以加劇這種銀紋隨時間的變化；經圖像處理，得到了不同基溫下、不同應力水平下， pmma試件銀紋損傷面密度值；進而，對所得數據進行非線性擬合，得到pmma試件銀紋損傷密度隨時間演化規律，以及應力水平依賴性； 3 -
Secondly, considering the complexity of the analysis of inclined - loading pile, nonlinear finite element method is adopted to calculate the internal force and displacement of pile group under inclined loads, with the concept of equivalent width presented to simplify 3d problems into 2d problems. and a program is developed as well, which is able to consider the continuity, elastic - plasticity and layered characteristic of soil around the pile shaft. besides, the interactions among pile, base slab and soil are considered in this program and contact surface element is used to simulate slipping and crazing between pile and soil, or between base slab and soil under loads. then, the non - tension analysis is proposed, to reflect the low - tensile property of soil and concrete
在此基礎上，針對傾斜荷載下群樁基礎分析中的復雜性，提出採用非線性有限元對傾斜荷載下群樁的內力及位移進行分析，應用樁的等效寬度概念將空間問題簡化為平面問題考慮，並開發出能考慮樁周土介質連續性、彈塑性、分層性等因素的傾斜荷載下群樁內力及位移分析的計算機程序，並在程序中考慮了樁、土、承臺的相互作用，提出了採用接觸面單元來考慮荷載作用下樁與土體及承臺與土體間的滑移、開裂；並在此基礎上，提出了傾斜荷載下群樁基礎的「無拉力」分析方法，可有效地反映土體及混凝土材料的低抗拉特性。 -
