Research on the Applicability of Metal Foam Based Sandwich Materials for Friction Stir Welded Ship Structures with Sufficient Fatigue Life Time

Research to analyse and/or develop novel materials and techniques is necessary to address competition and safeguard craftmanship in shipbuilding. In this master thesis, two new approaches to reduce the production and maintenance costs are studied: {metal foam core, metal face sheet} sandwich materials and corner adstir fillet stationary shoulder...
