At higher shock pressure, intragranular voids increase in fraction and tend to distribute at grain centers.
It is found that the sandwich plates have a higher shock resistance than monolithic plates of equal mass.
Meanwhile, the micro-switch can withstand a higher shock than the traditional designs whose cantilever beams are attached to the fixed electrode.
All the shock-deformed materials showed shock-strengthening that was greater at higher shock pressure and decreased with decreasing stacking fault energy (SFE) at both shock pressures.
The observed visual damage consisted of surface discolorations at low shock load levels and progressed to surface fiber breakage accompanied by internal delaminations and breakage of the through thickness (Z-directional) fibers at higher shock load levels.
Experimental results show the sandwich beams with aluminum honeycomb cores present mainly large global deformation, while the foam core sandwich beams tend to local deformation and failure, but all the sandwich beams had a higher shock resistance, then the monolithic beam.
