WebMay 16, 2013 · In this paper, we investigate flaw tolerance in a viscoelastic strip under tension and derive the conditions under which a pre-existing center crack, irrespective of its size, will not grow before the material fails under uniform rupture. The analysis is based on the Griffith and cohesive zone models of crack growth in a viscoelastic material ... WebIn many cases the documented height size provided by flaw manufacturers has a tolerance allowed of +/-2mm (+/-0.080”). Yet when the critical flaw size as determined by fracture mechanics is calculated, this often indicates a flaw on the order of 3mm in height for many projects involving pressure vessels and high-pressure piping.
