dc.description.abstract本文的主要目的是修正光彈等色線包裹相位圖,使相位展開技術能順利完成,進而得到我們須要得知的物理量-相對延遲量(主應力差)。在光彈法圓偏光架設中,應用相移技術求解等色線包裹相位圖,過程中發現包裹相位圖干涉條紋有”錯位現象” 。此現象使等色線包裹相位圖產生不連續點,且不利於相位展開進行。傳統做法為切除部分相移圖後,僅能作部分相位還原。本文解釋了相位圖干涉條紋”錯位現象” 的發生原因,及提出等色線包裹相位圖不連續點修正方法。最後以電腦模擬圓盤試片受壓狀態下之光彈模型,使用修正後等色線包裹相位圖執行相位展開,並與有限元理論解做比較可證明這些方法的可行性與準確性。zh_TW
dc.description.abstractThe main purpose of this article is to improvement of isochromatics wrapped phase map can make the phase to unwrap successfully and get the physical quantity we want to know, relative retardation. Phase-shifting techniques in photoelasticity have a peculiar problem of isoclinic-isochromatic interaction, which lead to ambiguous zones in phase map. These ambiguous zones produced inconsistency. These inconsistencies formed by ambiguous zones cause phase unwrapping failure. A comprehensive discussion on the reason for the formation of ambiguous zones is presented in this paper. A new method is developed to remove this inconsistency in the phase map. Finally, the computer simulation results obtained for disk-in-compression tests presented here in comparison with theoretical solutions demonstrate that these methods are both simple to use and very accurate.en_US
