The Accuracy on the Added Mass of Vibration by Boundary Element Method

Abstract

Many papers and applications about the boundary element method (BEM) were reported on the various fields, because of its easiness in the modeling and the economy on the calculation cost. The authors have already published new applications of BEM for the stress analysis and applied in practice. On the other hand, it is genallary said that the higher-order elements show the good accuracy, but there are few detail research for them. In this paper, the authors investigated the accuracy of the constant, linear, quadratic and those hybrid boundary elements on the added mass of vibration, and confirmed the super-parametric hybrid elements give the good results.
