... of GDLS with dependent failure modes. Based on the working principle of the GDLS, kinematic and dynamic model with imperfect joints is built in which Latin hypercube sampling (LHS) and kernel smoothing density are utilized to obtain the marginal failure probabilities. Then, copula models are utilized...

... and the mean time to failure (MTTF) of the system is obtained. A small electricity generating system is studied based on our method in the illustration, and detailed comparison result is made for dependent case and independent case. Dynamic reliability with varied levels of electricity generation conforming...

... simulation A sudden gas kick drops the pressure at the downhole due to a decrease in hydrostatic pressure while a well is open at the surface. In a closed well, the risk of casing failure caused by a sudden increase of the downhole pressure due to a gas kick significantly escalates the underwater...
