Would you reasonably run right into a brick wall or right into a mattress? For most individuals, the selection will not be troublesome. A brick wall is stiff and doesn’t soak up shocks or vibrations effectively; a mattress is smooth and is an effective shock absorber. Typically, in designing supplies, each of those properties are wanted. Supplies ought to be good at absorbing vibrations, however ought to be stiff sufficient to not collapse beneath stress. A staff of researchers from the UvA Institute of Physics has now discovered a approach to design supplies that handle to do each these items.
