Journal of the American Rocket Society, 1951 The purpose of this investigation is to demonstrate that the resistance of ceramic and ceramal materials to thermal shock can he determined by analyzing the nonsteady thermal stresses in the material. First the nonuniform temperature distribution is computed by using the heat conduction equation.

Thermal Shock Tests and Thermal Shock Parameters for Ceramics
Journal of the Korean Ceramic Society, 2012Thermal shock test methods and thermal shock parameters for ceramics were reviewed from the following viewpoints: (1) The test methods should be based on the precise estimation of both temperature and thermal stress distributions in a specimen taking into account the temperature-dependent thermo-mechanical properties; (2) The thermal shock parameters ...

SIAM Journal on Applied Mathematics, 1985
Ignition of an initially cold combustible gas is studied when chemical reaction is switched on due to the passage of a piston-supported shock of sufficient strength. The time and space history of the shocked gas up to the instant of thermal runaway is described, by using a combination of asymptotic and numerics.

Physical Review Letters, 2005
The Ludwig-Soret effect or thermal diffusion, which refers to the separation of liquid mixtures in a temperature gradient, is governed by a nonlinear, partial differential equation in space and time. It is shown here that the solution to the nonlinear differential equation for a binary mixture predicts the existence of shock waves completely analogous ...

Thermal equilibration in a shock wave
Physical Review Letters, 1992Absolute-intensity measurements of luminous emissions from shocked silicon show significant disagreement with predictions that assume thermal equilibrium between electrons and ions is reached immediately behind the shock front. Taking into account both electron-ion equilibration and electron thermal conduction, we have estimated an electron-ion ...

Thermal Shock and Thermal Fatigue Testing
Journal of Testing and Evaluation, 1991Abstract A method is described for rapidly screening candidate materials used in severe thermal shock applications. The method involves electron beam heating the surface of specimens using a thermal flux equal to that experienced during actual service operation. Two methods of electron beam radiation are described.

Thermal shock and dilution shock as the causes of freezing injury
Cryobiology, 1973Abstract We suggest that during slow freezing, cellular membranes are altered by the hypertonic solutions produced. This alteration in itself does not cause membrane leakage of normally impermeant solutes but it renders the cells susceptible to solute leakage on the application of a stress, which is provided during freezing by the reduction in ...

Thermal Shock Resistance of Skin Tissue
Journal of Medical Systems, 2010Understanding the mechanisms of skin behavior under thermal shock is crucial for medical treatments. However, no reasonable criteria are available for the maximum thermal loadings that skin tissue can survive. To address this, in this paper we analyzed thermal and neural behaviors of skin tissue exposed to thermal loadings by introducing the thermal ...

Thermal-shock resistant refractories and ceramics under thermal-shock conditions
Refractories, 1988We propose an approach to evaluating the thermal-shock resistance of solid bodies in a thermal-shock schedule based on the development of elastic waves of compression (expansion) and the final value of the velocity of the thermal waves. A model is put forward and also a calculation equation for the destructive drop in temperature ΔTp in the thermal ...
