| Abstract | The stress-strain characteristics and plastic behavior of aluminum alloy were examined by tensile test and infrared thermo-viewer. This thermo viewer is a device for converting a thermal radiation pattern from an object into visible images. Al-Mg alloy plates with different crystal grain size subjected to a uni-axial tensile load were measured continuously by this thermo viewer. The strain concentration pattern was analyzed by the differential thermal image and the macroscopic estimation method by the thermal image processing was proposed and the propriety of FE simulation based on polycrystalline plasticity model was shown. |
