Geometric correction factors determined by force balance method for center cracked specimens

“…In Part X of this series [1], the force balance method (FBM) has been applied to determine the geometric correction factor of the center cracked specimen loaded by linearly distributed stresses with the maximum value occurring at the crack tip. Such a case and the previously considered cases [2] may be used to account for fatigue crack closure effects, extrinsic toughening mechanisms like zone shielding and contact shielding [3,4], crack-face cohesive forces and/or bridging stresses in composite materials [5][6][7][8][9][10]• There are several types of crack bridging models in brittle-matrix fiber-reinforced composite materials, such as constant bridging stress [10], shear lag [11][12][13], fiber pressure [14] models.…”
