Simultaneous and Synchronous Full Field Deformation and Temperature Measurements in High Rate Events
Abstract
From the scientific point of view the work has been very successful. The results have been reported in a chapter in a text book, several scientific journal publications, and in a PhD thesis. The main practical goal of the work was to develop new measurement methods, which now has been completed and validated. The work has raised interest in the scientific community. From the material point of view the basic part of the project and the Option1 covered characterization of several materials, but at this point some of the results are not published yet, and more work and experiments would still be needed to finalize the originally planned research. The main findings of are given here, but a curious reader is referred to the references [1-5] for more details. We were successful in carrying out experiments at 1350 deg C at the strain rate of approximately 1600 s-1 for commercially pure titanium. This experiment was imaged with optical and infrared cameras, and we were able to carry out the full field analysis for the image data. This far exceeds the aims and goals outlined in the research plan. We carried out detailed analysis of the error sources and quantified the resolution and accuracy of the measurement as outlined in the research plan. We characterized the full thermomechanical behavior of the selected materials as specified in the original research plan. We are still carrying out experiments and will focus on inverse modeling approaches to quantify the material response. The research is therefore ongoing, but wont be reported here in details.
