Williams and Marshall [15] proposed a relaxation-controlled growth theory that correlates the fracture initiation time ([t.sub.B]) in SCG and the corresponding stress intensity factor K in polymers.
Stress intensity factor equation for cracks in three-dimensional finite bodies subjected to tension and bending loads, NASA Technical Memorandum 85793, National Aeronautics and Space Administration, Langley Research Centre, Virginia.
After a conventional analysis was done using idealized geometry and using a safety factor of 3 for strength, an initial semi-elliptical crack was introduced to determine the stress intensity factor of the crack-tip and the minimum fracture toughness value required for a safety factor of 3 (Fig.
where [K.sub.1] is the stress intensity factor (SIF) of the Mode I crack and r and [theta] are the polar coordinates relative to the crack tip.
The effect of the accumulative length [d.sub.[summation]] to the crack growth length curve is indicated in Figure 4(a), where the initial stress intensity factor [DELTA][K.sub.i] = 76 MPa [m.sup.1/2].
The stress intensity factor is employed to evaluate whether fracture happens or not as follows:
Later, they compared the Stress Intensity Factor (KI) obtained with the analytical values and with the values of X-FEM method.
Therefore, it was possible to calculate stress intensity factor for compact specimen according to the following equation (ASTM 2014):
A crack will grow if the stress intensity factor, due to the external load, [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] reaches the fracture resistance of the material, [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII], i.e., (Equation 7)
In this paper, the distributions of the mode I and mode II stress intensity factor solutions along the fronts of the pre-existing cracks of continuous and discontinuous gas metal arc welds in lap-shear specimens are investigated by three-dimensional finite element analyses.
Around a crack tip, the relation between the crack opening displacements and the extended stress intensity factors is [11,13]
Several methods have been proposed to calculate the stress intensity factors [K.sub.I] and [K.sub.II] for an oblique crack at the edge of a half-plane [7-12].
