Strain-energy release rate for a single-edge-cracked circular bar in tension

Abstract: The strain-energy release rate is determined for an edge crack in a uniformly stressed bar o f circular cross-section. Values o f the strain-energy release rate, obtained using a finite-element representation o f the bar and by measuring the compliance of the bar experimentally, are shown to be in close agreement. For crack depths of less than one-half diameter. the strain-energy release rates are found to be lower than existing results on rectangular bars having the same relative crack length. / Crack P A a =… Show more

In fact, the value 1.85 corresponding to a/D = 0.45 in this table will not be retained here as it is unreliable according to [8].…”

“…The results could be used to solve not only linear elastic fracture mechanics problems but stress corrosion, fatigue and corrosion fatigue problems. Because of this interest it is possible to find some recent references on the same I l l l 11111 or similar crack problem [13,[24][25][26][27][28][29]. Some authors use the finite element method [24,25,26], others the boundary integral equation method [13], experimental compliance measurements [25,27], fatigue crack propagation measurement [26], photoelastic stress analysis [29] or other numerical techniques [28].…”
