Abstract
A brick includes outer walls defining a hollow interior space, the outer walls including: substantially flat top and bottom walls; and side walls angled inwards toward a central portion of the NPR brick, such that application of a compressive force between the top and bottom walls causes a lateral dimension of the brick between opposite side walls to decrease. At least some of the outer walls of the brick include a material having a negative Poisson's ratio (NPR).
Claims20
A brick comprising:
- outer walls, wherein at least one of the outer walls is angled inwards toward a central portion of the brick, such that application of a compressive force between the top and bottom walls causes a lateral dimension of the brick to decrease,
- in which at least some of the outer walls of the brick include a material having a negative Poisson's ratio (NPR).
A brick wall comprising:
- an NPR brick configured to exhibit NPR behavior, the NPR brick comprising:
- first outer walls, wherein at least one of the first outer walls is angled inwards toward a central portion of the NPR brick;
- a positive Poisson's ratio (PPR) brick disposed adjacent to the NPR brick, the PPR brick comprising second outer walls, wherein at least one of the second outer walls is angled outwards away from a central portion of the PPR brick,
- wherein angled second outer wall of the PPR brick is nested within the angled the first outer wall of the NPR brick;
- and
- mortar disposed between the NPR brick and the PPR brick.
