Paper Abstract

Over the past few years, the luminescent photoelastic coating technique has been extended to acquire principal strain measurements on static, three-dimensional structural components under load. The approach uses oblique incident excitation and digital imaging of the luminescence; subsequent analysis is performed on a three-dimension grid compatible with finite element analysis. This paper discusses the initial efforts to extend the technique for dynamically loaded specimens in which the excitation is strobed in synchronization with the load application cycle.
