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(dǎo)致漆膜開裂、起泡;溫度過低使漆膜不易固化,出現(xiàn)流掛現(xiàn)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(jīng)圖像處理,得到了在不同應(yīng)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(guī)律。具體地, 1
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(jìn)行在線實時的圖像采集,經(jīng)圖像處理軟件的分析,得到了pmma試件在不同時間和不同應(yīng)力水平下的銀紋損傷面密度,并給出了pmma試件銀紋損傷面密度隨時間和應(yīng)力的變化而變化的規(guī)律。
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(xiàn)象進(jìn)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(guī)律,為研究pmma的細(xì)觀損傷提供了一種可行的損傷模型。
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在恒定荷載作用下,不同基溫下的pmma銀紋損傷進(jìn)行了實時在線觀測,結(jié)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(jīng)圖像處理,得到了不同基溫下、不同應(yīng)力水平下, pmma試件銀紋損傷面密度值;進(jìn)而,對所得數(shù)據(jù)進(jìn)行非線性擬合,得到pmma試件銀紋損傷密度隨時間演化規(guī)律,以及應(yīng)力水平依賴性; 3
