... ABSTRACT The aluminum honeycomb sandwich plates (AHSP) have been widely used in marine applications due to their excellent properties such as high strength/weight ratio. In the present study, the dynamic response of aluminum honeycomb sandwich plates under slamming loadings is investigated...

... and M64 and focuses on tests with high, representative mean stress levels. In addition to the results of fatigue strength tests, fractographic investigations of fracture pattern growth are also used.

The effects of blind-tee pipes on the gas-liquid bubble flow in different orientations are investigated, and detailed comparisons are made to reveal the differences between the single and two-phase flows in blind tees. It can help to further understand the multiphase flow...

Furthermore, also in the fatigue strength verification according to EC3 Part 1-9 (DIN EN 1993-1-9:2010-12, 2010), the increasing material strength and the connection configuration are not yet sufficiently...

.... Accordingly, the design of foundations must focus strongly on the effects of cyclic loads. For an investigation of partially drained conditions, which may arise during a storm event, 1g-small-scale tests can be carried out. The main problem with 1g-model tests is that for realistic drainage conditions...
