Dynamic Interaction between Ice and Inclined Structure

Interaction of Dynamic Cracks with Inclined Interfaces

Catastrophic failure of any brittle structure under dynamic loading consists of dynamic crack initiation, propagation, curving, branching (both micro and macro) and branching instability. However, the failure is much more complex in case of layered materials which has interfaces. In these materials, other than above crack mechanisms the crack can also deflect to propagate along the interface or...

Interaction of dynamic mode-I cracks with inclined interfaces

In this paper, we report on an experimental study of the deflection/penetration behavior of dynamic mode-I cracks propagating at two different crack velocities (slower and faster) toward inclined weak interfaces of three dissimilar angles (a): 30 , 45 and 60 . A simple wedge-loading specimen configuration as proposed by Xu et al. [Xu LR, Huang YY, Rosakis AJ. Dynamic crack deflection and penetr...

Coupled modeling of dynamic ice-structure interaction on offshore wind turbines

The offshore wind industry is growing at high pace and is already one of the major renewable energy sources in Europe. To support this growth, costs must be further decreased, amongst others by efficiently designing the support structure of the offshore wind turbines. This requires accurate prediction of environmental loading such as dynamic ice-structure interaction. From industry practice it ...

study of dynamic infinite element used for soil structure interaction

starting from two-dimensional (2d) equations of motion, discretized formulations for transient behavior of soil-structure interaction problems have been derived. two different dynamic infinite elements taking into account single and two-wave types are presented in transformed space. by coupling the infinite elements with standard finite elements, an ordinary finite element procedure is used for...
