Photoelastic Fringe Pattern Analysis by Image Processing
This work presents a strategy for automatic analysis of photoelastic fringe patterns. The study is focused on the analysis of color type photoelastic fringes. By capturing and analyzing color fringes automatically, the difference between principal stresses of a sample are quantitatively determined. Among many techniques available in literature, the color photoelasticity is chosen as the basis f...
متن کاملglobal results on some nonlinear partial differential equations for direct and inverse problems
در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
Results and Discussions
Calix (4) pyrroles are macromolecules structurally related to porphyrins, they exhibit exceptional chemical and physical properties that have suggested a vast number of potential applications in host-guest chemistry. In recent years, calix (4) pyrroles have attracted a lot of attention because of their properties as binders of anions, transition metals, and neutral substrates and their new appl...
متن کاملWindowed Fourier transform for fringe pattern analysis: addendum.
Novel approaches based on windowed Fourier transform for demodulation of fringe patterns were previously presented [Appl. Opt. 43, 2695-2702 (2004)], where extraction of phase and phase derivatives from either phase-shifted fringe patterns or a single-carrier fringe pattern was the main focus. I show that the same methods can be applied to process a single closed-fringe pattern in either noise ...
متن کاملPhotoelastic Fringe Pattern Analysis by Real-time Phase-shifting Method
This paper describes high-speed phase-shifting method for the real-time analysis of isochromatic and isoclinic parameters in photoelasticity. By rotating an analyzer at a constant rate and an output quarter-wave plate at a double rate of the analyzer and recording images by a CCD camera continuously, sequential phase-shifted images which brightness is integrated by sensors are obtained. Then, t...
