The bordure influence with flat-bars around the technological cut outs over the stress tension at an oil-tanker ship of 49000 tdw
Keywords:
finite element method, deformations, static analysis, stress concentration, normal stress.
Abstract
The purpose of this paper consists in analysing the bordures influence with flat - bars around the technological cut outs on hot-spots stress. This static calculation was performed by the finite element method with Femap software as modeller and NX Nastran as solver. It is recommended the use of the bordures at the technological cut outs because the tensions decrease considerably, eliminating the risk of dangerous tensions.
