Visualization and quantification of the stress distribution on epoxy resin through photoelasticity and infrared radiation techniques
Source abstract
Abstract
To investigate the applicability of infrared thermography as a method for acquiring dynamic stress distribution in epoxy resin, a comparison of infrared radiation thermography with the photoelasticity technique has been made. A series of four-point bending tests of epoxy resin have been performed to evaluate the stress obtained by infrared radiation and illustrate the capabilities and accuracy of the proposed methods. To compare the stress distribution and evolution of epoxy resin detected by two methods, the experimental results show the validity and reliability of infrared radiation thermography in visualizing and quantifying the distribution and evolution characteristics of solid materials. This research was based on two basic tests, the results indicated that infrared radiation thermography is effective in exploring the dynamic distribution and evolution of stress on solid materials. The proposed testing method is effective in exploring the distribution and evolution of stress on different solid materials.
