<p>The thermal shock behavior of a high-temperature ceramic plate with indentation crack was studied. The analytical solution of temperature field is obtained by the standard method of separating variables. The total stress intensity factor at the front of semi-elliptical indentation crack is evaluated by thermal stress and residual stress intensity factors. The thermal stress intensity factors in the depth direction and the surface direction of the semi-elliptical indentation crack front were obtained by fitting the polynomial form of the thermal stress and crack geometry factor. The residual stress intensity factor was related to indentation load, crack shape and length, elastic modulus and hardness of the material. The graphs of the total stress intensity factor and the thermal stress intensity factor were obtained by calculating the analytical solutions using MATLAB. The results were compared. The results provide a theoretical basis for studying the thermal shock fracture of indentation crack. The thermal shock resistance is evaluated by the strength failure criterion and fracture toughness failure criterion.</p>
