1. An airplane runway mat, comprising:
a base portion having a first plurality of spaced columns extending therefrom;
a loading platform portion having a second plurality of spaced columns extending therefrom;
wherein the base portion and loading platform portion are matably interconnectible;
wherein each respective column defines a plurality of operationally connected phase transforming cells;
wherein each respective cell has a first and a second stable geometry; and
wherein energy transfer is required to shift from one stable geometric configuration to the other;
wherein each respective phase transforming cell is steel and wherein each respective base plate is a steel/aluminum composite.
