The thermo-mechanical response of rectangular Hastelloy X plates at different angles of shock impingement was experimentally studied. The shock tube apparatus was modified to experimentally investigate Hastelloy X at elevated temperatures and at 0° ,15° and 30° shock impingement angles. A series of experiments were conducted at room temperature, 400°C and 800°C for each shock impingement configuration. The deformation process was captured using two high speed cameras and the Digital Image Correlation (DIC) technique was used to obtain real-time displacement and strain fields. The optical band pass filters were used in conjunction with a high intensity light source to record the deformation process during the high temperature experiments. The DIC technique was validated by comparing the deflection of the midpoint on the side of the specimen with the deflection obtained from side-view camera. The dynamic response of Hastelloy X under shock loading was evaluated as a function of shock impingement angle and temperature.
