Kinetics and Mechanism of Cracks Formation in Rubbers

摘要

The regularity of cracks formation had been concluded from precise experimental data. The mean value of crack surface was used as a measure of cracking degree. It was shown that the rate of cracks surface growth consists from two stages: a relative slow one at beginning of test and a faster one on the second stage. It was running with constant rate. A probable explanation of experimental observation and kinetic law of process was given. The amount of ozone consumed per 1 cm~2 of crack surface formed was counted (calculated) and found to be ～8 *10~(-10) mol/cm~2 what is about 1 % of the total amount of ozone absorbed by the sample.
