The paper presents a view on selected problems concerning application of steel sandwich panels to marine structures. Such problems connected with specificity of thin-skin laserwelded structure are varying in topics beginning from micro-scale properties of laser-welded T-joint through the joining of sandwich structures together up to connection and integration of such structures with a classical single-skin structure.

“…Many researches have been conducted on metallic thermal protection system, including the design and characterization of thermal insulation material/structure [3][4][5][6][7][8], however, rare studies have been done on heat shorts blocking joints. In addition, most researches focused on metal joints [9][10][11][12][13][14][15], which had quite poor heat insulation properties. Some studies were carried out on C/SiC joints [16][17][18], yet the complicated fabrication approaches for geometrically complex composites such as bolted joints have certain limitations in terms of size and shape, which have greatly limited their wider applications.…”

Metal-ceramic functionally graded materials (FGMs) have been extensively used in aerospace engineering where high strength and excellent heat insulation materials are desired. In this paper, load distribution in threads of the Thermal Protection System used bolted joint made up of porous ZrO2/(ZrO2+Ni) FGMs is investigated by ABAQUS codes. The bolted joint is subjected to reentry heating corresponding to the Access to Space Vehicle. Effects of bolt-nut parameters including thread tooth profile, thread pitch, and modulus ratio of bolt to nut on load distribution in threads are analyzed in detail. It is found that uneven load distribution in threads occurs at elevated temperature, which mainly focuses on the first two threads closest to the nut bearing surface, with the first thread carrying 74% of the total load. Bolt-nut parameters have great effects on load distribution in threads, with trapezoidal thread, extra fine thread and greater modulus ratio of bolt to nut leading to more evenly distributed load. Further studies show that nut shape has significant effects on load distribution in threads, the optimized nut is designed to make the maximum load bearing ratio of the thread decrease to 30.21%, and thus the service reliability of the bolted joint is greatly improved.

“…This technique permits real-time visualization of a deformation event, as well as the determination of geometric properties (e.g., the displacement and strain history) by tracking the minute changes on the area of interest. With the advancement in digital imaging technology, there has been a strong effort to develop a robust photogrammetric technique for real-time mechanical deformation analysis (3-5) in a broad range of materials characterization including biomechanics (6, 7), structural engineering (8,9), and ballistics (10)(11)(12)(13). Results from the local strain deformation measurements will also be used for correlation with the corresponding viscoelastic relaxation data.…”
