Abstract: A strain distribution measurement system includes a tensile tester that deforms a test piece to measure mechanical properties of a material of the test piece, and a strain distribution measuring device that measures a strain distribution of the test piece. The strain distribution measuring device measures the strain distribution of the test piece based on a distribution of at least one of a reflectance or a polarization characteristic on the main face of the test piece.
