Experimental research on over-laminated steel sandwich panel connection to determine the form of fatigue failure

Abstrakt

The novel means of transport need to meet rising both the economic and ecologic requirements. In recent years the International Maritime Organization (IMO) introduced new measure of ship energy efficiency (the EEDI index), as well as new regulations regarding higher quality of fuel (so called Tier limits). It resulted in much higher interest of the technological development of ships. One of the solution having great potential is the reduction of structural mass. It has at least two positive consequences. The first is the reduction of fuel consumption, the second is possibility if increasing of a ship payload. Both aspect are very beneficious considering the need of meeting the EEDI requirements. The one very lightweight form of structure which is in use in many different branches are sandwich type structures. In a shipbuilding industry this solutions is also being constantly developed. One of the major issue for these thin walled structures is connection between panels and between panels and an ordinary ship structure. For rising fatigue resistance of the connection the over-laminated joint concept was introduced. In this article results of fatigue research on sandwich panels joint with the CFRP overlays are presented. The experimental research was performed in a full scale to identify the form of fatigue failure. On the basis of the research three characteristic stages of fatigue damage were identified.
