FATIGUE PROPERTIES OF LASER WELDED STEEL SANDWICH PANELS

摘要

Laser welding techniques start to find their position among different methods of joining which allow changes in configuration of typical ship structure: instead of shell plating supported by perpendicular system of heavy stiffeners a SANDWICH panel - two shell plating of thickness in the range 3-4 mm with height about 40 mm, supported internally by uni-directional system of stiffeners connected by laser welding- offers quite new solution. Paper presents idea of the SANDWICH panels as well as the laboratory fatigue tests results of such panels tested in natural scale.
