Webb13 apr. 2024 · This paper is the third in a series of three on crack growth in viscoelastic media. The first (Schapery 2024a) is concerned primarily with the effect of various models of the failure zone (FZ); i.e. the very small crack-tip process zone where the material comes apart.Using linear theory for the continuum, it is shown that the primary effect of the … WebbThe storage modulus gives information about the amount of structure present in a material.
