“…A previous study [11,13] showed, from both experimental and numerical results, that the impact force resulting from the same impact loading condition was much larger when the carbon-fiber composite plate was under the water than in air. The test was conducted without causing damage to the composite plate so that the dynamics response without failure could be compared between the submerged and dry structures.…”

Damage initiation and growth as well as dynamic response of laminated polymer composite plates were investigated with the effect of Fluid-Structure Interaction (FSI) when they were subjected to impact loading.The E-glass composite plates were clamped along the boundaries and impact loading was applied from a specially designed vertical drop-impact testing machine while the plates were surrounded by either water or air.The damage and transient responses such as force-and strain-time history were measured during the progressive impact tests, and the test data collected from either impact in air or under water were compared to determine the effect of FSI. The study showed that FSI was generally detrimental to composite plates because of the hydrodynamic mass effect so that damage occurred at a lower impact force for the composite plate submerged in water. The strain measure also suggested that the FSI effect varied from location to location of the plate surface. Additionally, the FSI effect yielded a significant change in the strain response in terms of both magnitude and shape in time history for the plate in water along with progressive damage. In summary, it is essential to include the FSI effect for design and analysis of composite structures when they are in contact with water.

“…Low density including corrosion resistance makes composite materials a good choice for many watercraft applications [26,27]. Unlike the 'standard' materials, composites are prone to specific types of damage like delaminations [28,29]. Delamination present in layered material can be completely invisible on the surface.…”

The paper reviews thermographic and vibrothermography applications such as cold climate operations, determine the temperature profile of steel samples under tensile testing and perform composites Non-Destructive Testing (NDT). This review paper discusses studies, where IR thermography has been used effectively in research and development projects at the UiT The Arctic University of Norway and AGH UST. The applications discussed in this work are to determine: • Thermal conductivity and heat transfer coefficient of freshwater and marine ice • An industrial solution for detecting icing • Relative required insulation (IREQ) of apparels • Variation of tensile strength and surface temperature of steel samples under tensile testing under cold temperatures • Vibrothermography for Non-Destructive Testing (NDT) of composites
