The discussion focuses on the stress-strain relations in thermo-elastic materials experiencing thermal shock with crack mode I propagation. The stress induced by thermal shock is calculated using the material's modulus, temperature change, and coefficient of thermal expansion. It is established that crack propagation occurs only if the stress exceeds the critical stress intensity factor K divided by 2.5 and the square root of the crack depth.
PREREQUISITESMaterials scientists, mechanical engineers, and researchers focused on crack propagation and thermal shock effects in thermo-elastic materials.
If I understand your question correctly, the stress from the thermal shock is the modulus of the material times the temperature times the coefficient of thermal expansion. As long as the stress is less than the critical stress intensity K divided by 2.5 divided by the square root of the crack depth then the crack will not propagate.mohammed El-Kady said:Summary:: the stress strain relation
If i have a thermal shock in a thermo-elastic material with crack mode I propagated ? what are the stress-strain relations in this case? or what is the factor K relation? "sorry if the question is not true, but i hope you understood what i mean"
