In failure time distributions, inliers in a data set are subset of observations sufficiently small relative to the rest of the observations, which appears to be inconsistent with the remaining data set. They are either the resultant of instantaneous failures or early failures, experienced in many life-testing experiments. The model used in outliers, where r observations are outliers is modified...

This study presents reviews of the failure criteria to capture resulting response due catastrophe ship collision and grounding using finite element. Researchers have introduced several criteria, for instance, DNV RP-C204 criterion, Germanischer Lloyd Peschmann, RiceTracey Cockcroft-Latham (RTCL), Bressan-Williams-Hill (BWH) instability Liu criterion. As in mathematical formula, each criterion h...

During a mission, detecting failure accurately and implementing countermeasures in time may decide the success of a space mission. Chang’E-1 mission is the first lunar exploration mission of China. The satellite has several different telemetry formats and bit rates. Moreover, the accuracy requirement of orbit control is high and demands real-time handling during contingency or abort operations....

A rock failure criterion is very important for prediction of the ultimate strength in rock mechanics and geotechnics; it is determined for rock mechanics studies in mining, civil, and oil wellborn drilling operations. Also shales are among the most difficult to treat formations. Therefore, in this research work, using the artificial neural network (ANN), a model was built to predict the ultimat...

Strength of rocks in the confined tension region, where minimum principal stress is tensile, has only infrequently been measured and not well understood. Quasi-static Brazilian tests under a range confining stresses (2.76 to 27.58 MPa) used determine strength sandstone region. The test results indicate that region was strong function intermediate stress: increasing significantly increased sands...
