CERN and the Taming of the Zoo,water, or a liquid with a different speed of sound are considered and the specific issue considered is the prediction of the position of the various wave fronts as a function of time. This is a challenging problem for both analytical and numerical approaches due to the sharp discontinuities, the com

https://doi.org/10.1007/978-3-540-88812-3 the complex mechanisms of damage initiation and propagation under low velocity impact loads. A review of the main results is hereafter presented..The problem is that many parameters are involved in an impact and the induced damage is very complex and not always visible. The present research efforts

Sedonalgesierung bei Langzeitbeatmeten, scientific literature to model the behavior of composite laminates subjected to high-velocity impact of low-mass projectiles is presented, and a new analytical model is proposed. The present model is able to predict the energy absorbed by the laminate during the perforation process including the ma

Reinhard Larsen,Thomas Ziegenfuß the demonstration that Nomex honeycomb behaves in a post-buckling mode very early and that compression forces are taken up by the corners or vertical edges of the honeycomb cells in the same way as they are in the stiffeners in aircraft structures. Thus it is possible to represent the honeycomb dis

Reinhard Larsen,Thomas Ziegenfußes are produced by folding a flat sheet of material to three-dimensional zigzag structures in an origami-like manner. Relevant cell wall materials range from cardboard to plastics, from metals to composites. Different manufacturing processes and feasible cellular configurations are presented based o
