In the Previous study, two Inside Temperature (IT-a and IT-b) methods for estimating the temperature distributions in steady wave fronts in a thermo-viscous material were established and the IT-b method was shown qualitatively to be effective if the effect of viscosity was distinguished. In this paper, these two methods are applied to the shock compressions of Yittria-doped Tetragonal Zirconia (YTZ) that is a thermo-viscous material with a multiple shock Hugoniot. The YTZ Hugoniot consists of three partial curves including two kinks, that are the Hugoniot Elastic Limit (HEL)and the phase transition point. The shock temperatures evaluated by the IT-b method were close to the accurate temperatures obtained by the Shock-Temperature method in the whole stress range to 140 GPa examined here. Furthermore, the inside temperature distributions were approximately accurate because the effect of viscosity was distinguished in the shock compression. By these facts, it was considered that the fundamental assumption and the assumption on heat transport used in the IT-b method were valid and as a result, this method was effective. In addition, the influences of heat transport on the temperatures and thermo-elastic stresses were examined.
