In this paper, a novel version of orthonormal polynomial series expansion method is developed to analyze vibrations of bottom hull panels due to moving impacting fluid loads. The vibration of hull panels subject to slamming loads has been analyzed using a new version of orthonormal polynomial series
expansion method. In the presented version of the orthonormal polynomial
series expansion method, an efficient framework is proposed to
attain the response of the structure. The developed method does not
require employing higher derivatives of orthonormal shape functions to
post-process the displacement field and internal forces. In return, it is
based on the successive direct integration of the shape functions and
pressure function. Consequently, the Gibbs effects are remarkably suppressed.
The number of contributing orthonormal shape functions has
been widely probed in the computation of beam deflection, flexural
moment and shear force for both the developed modified orthonormal
polynomial series expansion method and the conventional method.
Being free of spatial derivatives of basic orthonormal polynomials,
