EXPERIMENTAL EVALUATION OF THE CRACK RESISTANCE OF GLASS-FILLED POLYAMIDE UNDER COLD CLIMATIC CONDITIONS F. I. Babenko and A. K. Rodionov UDC 678.067.5.017 We show that a correct evaluation of the effect of various factors of a cold climate on the crack resistance of a material is not possible without account for the dependence of the coefficient K1c on the effective rate of loading of a specimen that has a notch-crack.
