Experimental stress analysis of unsymmetrical, irregularly-shaped structure containing an arbitrarily-shaped hole

Abstract

This paper describes the ability to process load induced temperature information with an Airy stress function in real polar coordinates and some local known boundary conditions to determine the stresses experimentally in an isotropic linear elastic finite arbitrarily-shaped structure containing an irregularly-shaped hole. The proposed method simultaneously smooths the measured data, separates the stress components, and evaluates the individual stress components full-field, including at the boundary of the hole (location of highest tensile stress). © 2018, The Society for Experimental Mechanics, Inc.
