The Effect of Partial Closure on the Stress Intensity Factor of a Griffith Crack Opened by a Parabolic Pressure Distribution,

摘要

The problem of a Griffith crack in a thin plate,which is opened by a parabolic pressure acting on its surfaces is considered. The crack is then partially closed in a symmetric manner by ties,idealized by point loads in the material,and the effect upon the stress intensity factors is discussed. (Author)
