【 摘 要 】

Recently, simple non-singular stress fields of cracks of mode I and mode III have been published by Aifantis (2009, 2011), Isaksson and Hagglund (2013) and Isaksson et al. (2012). In this work we investigate the physical meaning and interpretation of those solutions and if they satisfy important physical conditions (equilibrium, boundary and compatibility conditions).
