Submodeling Analysis of Ship Structure with Super-convergent Patch Recovery Method

摘要

The new submodeling technique is proposed and is appliedto ship structure analysis in which Bulk Carrier is selected inthis paper. Two types of boundary conditions, one is displacementboundary condition and the other is stress boundary conditionbased on superconvergent patch recovery (SPR) method,are applied in submodeling analysis and their results are compared.Two computational domains of ship structure for submodelinganalyses are considered and the accuracy of the submodelinganalysis is investigated. According to the numericalanalysis, SPR method improves the stresses along the submodelingboundary and the proposed submodeling technique givesaccurate solutions.
