Nonlinear effect on wave loads of large ships in time domain

International Journal of Naval Architecture and Ocean Engineering, 2011
As sea state harsher in the ocean space, more large motion and wave loads occurs on ships hull by non-linear phenomena. To consider nonlinear effect on ships hull in the structural design verification, the direct calculation method with numerical ...

Nonlinear thermo-mechanical bending analysis of variable-thickness parallelogram plates in curved hull via a homotopy-based wavelet method

Applied Ocean Research
Due to the variable-thickness parallelogram plates in ocean structure are characterized by the presence of strong moment singularity at supported obtuse corners, the wide application has turned the nonlinear mechanical analysis into one of the most ...

Vertical Bending Moment in Extreme Regular Waves—Benchmarking of Numerical Codes Against Model Tests

Journal of Marine Science and Engineering
A benchmark study of 10 different numerical methods for ship motion and load assessment is presented. Pitch motions and midship vertical bending moments are compared to model test results for a containership at zero speed in head regular waves.

Nonlinear Deformation Analysis of Sandwich Timoshenko Beams with Carbon Nanotube Reinforced Face Sheets and Re-Entrant Core Using GDQ Method

Mathematics
In this research, the nonlinear bending behavior of sandwich beams with auxetic re-entrant cores and carbon nanotube-reinforced (CNT) face sheets are investigated using the von Kármán strain theory and the Generalized Differential Quadrature (GDQ) method.

Broadband frequency response of a nonlinear resonator with clearance for energy harvesting

MATEC Web of Conferences, 2018
We examine the response of an inverted pendulum excited harmonically with amplitude limiters. Such a nonlinear resonator is suggested to work in the transduction of ambient vibration energy into the electrical power through bending of the moving beam ...

Homogenization of the nonlinear bending theory for plates

, 2013
We carry out the spatially periodic homogenization of Kirchhoff's plate theory. The derivation is rigorous in the sense of Gamma-convergence. In contrast to what one naturally would expect, our result shows that the limiting functional is not simply a quadratic functional of the second fundamental form of the deformed plate as it is the case in ...
