“…Interface problems, either, free-surface [5,6], a thermally coupled analysis considering phase-change [7,8], or even, solid mechanics problems with stresses location, damage or plasticity [9,10,11], are promising cases where the use of adaptivity is relevant because thin layers of the full domain contains the most important information of the global behavior of the problem. In this work an adaptive xed-mesh ALE method is used to numerically approximate the sloshing of a rectangular tank partially lled with a domestic oil subjected to a controlled movement generated by a shake table.…”

This work reports an experimental and numerical analysis of the sloshing of a squared tank partially lled with a domestic vegetable oil. The tank is subjected to controlled motions with a shake table. The freesurface evolution is captured using two experimental techniques: ultrasonic sensors and an image capturing method. The data obtained using these two techniques are compared between them and used to conrm the measurements. Only conrmed data within the error range are reported. Filling depth, imposed amplitude and frequency eects on the sloshing wave pattern are specically evaluated. The experiments also reveal the nonlinear wave behavior. The material properties of the oil are also determined. The numerical model is based on a stabilized nite element method of the Variational Multi-Scale (VMS) type. The free-surface is captured using a level set technique particularly developed to be used with adaptive meshes in Arbitrary Eulerian Lagrangian reference frameworks. The experimental and numerical results are compared for dierent sloshing conditions near the rst sloshing mode. The simulations satisfactorily match the experiments, providing a reliable tool for the analysis of this kind of problems.

“…Many structural composite components require the inclusion of open holes to allow the access of electric wires, hydraulic pipes, assembly or maintenance activities. However, the sensitivity of a composite laminate to a notch is dependent on a large number of parameters: laminate size and thickness, notch size and geometry, width/diameter ratios, ply orientation and thickness, machining quality and material properties . All of these factors affect the mechanical properties by changing the extent of damage growth during loading, and interact with each other to enhance the individual effects .…”

Multi‐impact response of composite laminates with open holes

et al. 2016

The multi-impact response of glass-epoxy composite laminates with open holes was studied. For this purpose, plates without any hole and containing one or two holes were tested under low velocity multi-impact loading to assess the influence of holes on the damage development. Experimentally, it was verified that the maximum load and the dissipated energy decrease with the number of impacts, while the displacement increases for all cases. In addition, the presence of holes revealed to have an important influence on those parameters. A three-dimensional finite element analysis including a cohesive mixed-mode damage model was also performed to better evaluate the interaction between the resulting delamination and the presence of holes. It was observed that the existence of holes alters the delamination profile and contributes to increase its size especially in the case of two holes. It was concluded that special attention should be given to structural applications requiring open holes and eventually submitted to impact loads. POLYM. COMPOS., 39:2490-2498

As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. In terms of multi-impacts, the damage severity is also very influenced by the distance. For small distances the damage progresses quickly, while three stages can be found for the control samples and for the distance of 20 mm. Effect of distance between impact
