mechanical test system at the strain rate of 1 mm/min. Here, typical microstructure of the bended specimen before and after the
plastic deformation.
One may observe from these pictures that an internal crack at the centre of the sandwich structure after the passage loading
limit of the materials. This type of crack occur randomly during the overload conditions.
