termotsüklilisest koormamisest põhjustatud materjali pragunemine (vt termoväsimus)
cracking resulting from the presence of temperature gradients that vary with time in such a manner as to produce cyclic stresses in a structure (see: thermal fatigue)
Hea teada
Thermal fatigue cracking may cause, as an example, in "heat checking" - formation of fine surface cracks, as a result of thermal fatigue in metal forming and casting dies.
