AbstractThe formation of cracks in constant stress creep tests and variable stress strength tests using a common rheological model is discussed. The results of tests conducted on ice specimens and deformation equations proposed for various loading conditions are used to show that the formation of cracks is the result of critical delayed elastic strain. The findings confirm the hypothesis that delayed elastic deformation is linked to grain boundary sliding. It is shown that the degree of stress depends on the initial cracking time and that the minimum stress required to initiate cracking can be predicted.
