in this article, finite element method and ale formulation were used to numerically simulate impact of low-velocity specific projectiles with water surface. for the simulation, ls-dyna finite element code was used. material models which were used to express behavior of air and water included null material model. for the projectile, plastic-kinematics material model was applied. mie-gruneisen eq...

This review paper presents the recent advances in numerical modelling of wave–structure–seabed interactions. The processes that are involved wave–structure interactions, which leads to sediment transport and scour effects, summarized. Subsequently, three most common approaches for is induced by interactions described. applicability each approach also included with a summary studies. These based...

The effective pair potentials between different kinds of dendrimers in solution can be well approximated by appropriate Gaussian functions. We find that in binary dendrimer mixtures the range and strength of the effective interactions depend strongly upon the specific dendrimer architecture. We consider two different types of dendrimer mixtures, employing the Gaussian effective pair potentials,...

Following the accident involving the Air France Concorde in 2000 the effects of fluid structure interactions resulting from the impact of a fluid filled tank has become a cause for concern. The work reported here relates to the design of a series of experiments loosely based upon the Concorde incident which aimed to assess whether the probable failure mode in the Concorde accident could occur i...

The simultaneous effects of soil and existing structures are known as the site-city interaction (structure-soil-structure). The impact of site-city interaction on structure behavior is effective. Thus, this interaction in some regions decreases the responses while increases in other areas. In addition, the site-city interaction of many parameters including the soil type, density rate, height of...

In this paper, an algorithm that generates volume fraction initialisation for fluid-structure interaction problems is presented and implemented in an Arbitrary Lagrangian Eulerian (ALE) code. This algorithm improves the flexibility and efficiency of multi-material ALE formulations, enabling fluid-structure coupling problems to be dealt with, in which complex-shaped structures are embedded in a ...

Four data-driven low-order modeling approaches, Dynamic mode decomposition (DMD) and three other variations (optimal decomposition, total-least-squares DMD high-order DMD), are used to capture the spatio-temporal evolution of fluid–structure interactions. These methods applied experimental data obtained in a flow over flexible membrane wing its elastic deformation. Spectral coherence indicates ...
