The calculated first-order response function of motions,motion spectrums and statistical values of surge,heave and pitch motions were compared with the corresponding ones in model test.
Study on the mechanism of instability and failure of this kind of structure is an unsolved topic and a research full of challenge in the field of numerical analysis.
In some cases, including analysis on Euclidean space, sphers, hyperbolic space, and certain other symmetric spaces, exact formulas for fundamental solutions to wave equations are available.
For the analogs of the heat and wave equation, we give algorithms for approximating the solution, and display the results of implementing these algorithms.
On studying traveling waves on a nonlinearly suspended bridge, the following partial differential equation has been considered: uu+uxxxx+f(u)=0, where f(u)=u+-1.
This paper considers the generalized KdV equation with or without natural boundary conditions and provides a parameter region for solitons and solitary waves, and also modifies a result of Zabusky's.
In this paper we described and discussed the experimental results of two new types of concrete armor units which were created and studied by us to meet the practical needs of harbor construction and shore protection engineering in our country. One of them, the wing type of armor, is principally applicable to breakwaters, and the other, the frog type of armor, to shore protection engineering. Model exper- iments indicated that the wave-resisting characteristics of both types of armor are superior, their tech...
At present the super-depth ⊿h due to motion of moored ships produced by waves action is usually estimates at 0.5H, where H is the wave height in front of the quay for mooring. This may be feasible for short period waves, but it is slightly insufficient for longer period waves.
In practice, how to determine the stability and wave dissipating effect of rubble-mound breakwater under wave action is a very important problem. In our test, we not only considered the general factors, such as wave hieght, wave length, water depth at the breakwater toe, breakwater slope, which were usually considered by other researchers, but also consider the effect of the vertical distance from stillwater level to breakwater crest and the width of breakwater. The results can be used to calculate the stab...
