Study of Experimental Stress Analysis
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 4
Abstract
This paper gives brief information about experimental stress analysis methods with the help of polariscope. Experimental stress analysis contains various methods of stress analysis which are more convenient and accurate than the analytical and numerical methods. This paper is very useful for understanding the basic concepts and basic methods of stress analysis by experimental method. For this analysis we use the preferred specimen for calibration, axially loaded circular disc with its center as a point of interest for our analysis. First of all we make circular photo elastic model. For convenience mark the center of this circular disc as a point of interest. By observing the isoclinic’s we find out the direction of principal stresses at the required point. Then by using Tardy’s method we find out the fractional fringe order at the point of interest. By substituting this information in stress optic law we get stress difference. Among the various methods of stress separation such as electrical analogy, shear difference, method based on Hooke’s law, oblique incidence we use the oblique incidence method. Because with the help of polariscope only this method we can use for stress separation.
