Sandwich Structures - an overview | ScienceDirect Topics
Hence, core shear failure may likely emerge from centre line of the beam structure due to the maximum shear stress at that point. This argument can be proved by fatigue tests of sandwich beam structures with a foam core material under three-point beam bending test (Johannes and Thomsen, 2009). Small fatigue cracks are accumulated at the centre line of beam structure in maximum shear region and they …
