... ABSTRACT Flow around a ship that advances at a constant speed in calm water of finite depth is considered within the usual framework of the Green-function and boundary-integral method associated with potential-flow theory. This method requires accurate and efficient evaluation of flows created...

... reduce the fatigue behavior, so that the prevailing fatigue classification may not be valid. Using different steel grades, non-load-carrying attachments were wet SMAW welded at different water depths. The samples were fatigue tested and statistically evaluated. The fatigue strengths were found to be very...

... ABSTRACT The rainfall simulation in General Circulation Models (GCMs) is crucial in hydrological applications. In this study, the accuracy of rainfall from 15 GCMs in CMIP6 is evaluated over the Yangtze Delta. The results demonstrate that these GCMs can reproduce the seasonal cycle. However...

... wells in the region. Restricted by the large error of pressure prediction and the complexity of temperature and pressure system, drilling engineering accidents occurred frequently, which cost 4.95 billion yuan but did not achieve the purpose of drilling. complex reservoir evaluation south china...

... compressibility vm or compression index are considered to contain a significant amount of secondary compression. In one-dimensional consolidation analysis considering secondary compression, there is a possibility of predicting an excessive total consolidation due to the double evaluation of the secondary...
