Latest Patents

One of Smith's latest patents is for strain-detecting composite materials. This invention involves a composite material that includes a structural material and a shape-memory alloy embedded within it. The shape-memory alloy is designed to change its crystallographic phase from austenite to martensite in response to a predefined critical macroscopic average strain of the composite material. In another embodiment, the composite material incorporates a plurality of particles of a ferromagnetic shape-memory alloy, which also changes its crystallographic and magnetic phases in response to strain. The method for forming this composite material involves providing the shape-memory alloy in its austenite phase, altering its size and shape, and combining it with the structural material at elevated temperatures.

Another significant patent by Smith is a system for repairing cracks in structures. This invention involves a first material that is coated with a second material on at least one surface. The coating has a melting temperature that exceeds the maximum operational temperature of the first material. When heated to its melting point, the coating flows into any cracks present on the surface of the first material, effectively sealing them.
