Suction caisson foundations provide options for new foundation systems offshore structures, particularly wind turbine applications. During the design process, it is necessary to make reliable predictions of stiffness foundation, since this has an important influence on dynamic performance overall support structure. The characteristics structure, in turn, its fatigue life. This paper describes a...

Modeling of large amplitude of structures such as slender, flexible cantilever beam and fluid-structure resting on nonlinear elastic foundations or subjected to stretching effects often lead to strongly nonlinear models of Duffing equations which are not amendable to exact analytical methods. In this work, explicit analytical solutions to the large amplitude nonlinear oscillation systems of cub...

This paper presents exact solutions for the nonlinear bending problem, buckling loads, and postbuckling configurations of a perfect an imperfect bioinspired helicoidal composite beam with linear rotation angle. The is embedded on elastic medium, which modeled by two foundation parameters. integro-differential governing equation system derived based Euler–Bernoulli hypothesis, von Kármán strain,...
