See How Surface Tension Helps Crack The Toughest Cases

May 1, 2012 · the dependence of the crack line tension on the crack size is analyzed for the conformal change (when a crack changes its size with maintaining its geometrical similarity). Mar 1, 2016 · we show that surface tension resists crack growth by lowering the applied energy release rate while retaining the inversely square root singularity of the elastic crack tip field. This paper has demonstrated that the transformation toughness phenomenon exists for a motionless crack due to the zone boundary’s surface tension. Provided the process zone. Feb 5, 2021 · we demonstrate that the zone extends backward beyond the crack tip due to the zone boundary surface tension.
