"Therefore, N.H.T.S.A. will issue an initial defect decision, the next step toward a forced recall".
Because the initial defect was round in shape with an 8.0-mm diameter, the region of interest (ROI) was set based on the initial defect size and shape.
It was not possible to evaluate the initial defect size and morphology.
The model gives reasonable estimations for the crack growth of an initial defect.
The main parameters (migration energy, initial defect concentration, diffusion time) are estimated from available experimental data.
In case of one defect, the correlation between the initial defect depth and the initial defect length has the most significant impact on the failure probability of the pipeline.
As relative high safety margin was achieved, a complementary assessment postulating an initial defect of 6 mm was also conducted.
The different effects of various influencing factors (including early-age micro crack or initial defect of concrete, etc).
Subsequently, the initial defect tensor for polycrystalline ice is obtained from the initial defect tensor for a single grain of sea ice and the probability distribution of thec-axis.
An initial defect tensor for a single grain of sea ice is defined by using the geometric pattern.
In comparison, the role of the initial defect content, linked to the crystal size, has been given less consideration.
