Ultrasonic additive manufacturing (UAM) is a solid-state additive and subtractive
manufacturing process that utilizes ultrasonic energy to produce layered metallic parts.
The process is easily extended to create advanced multi-material structures, e.g., metal
matrix composites, functionally graded metallic components, and shape memory alloys.
This research utilizes a three point bending test to compare the elastic modulus in metal
matrix composites (MMC’s) specimens consisting of stainless steel wire reinforcements
with an aluminum matrix to unreinforced test specimens; both specimens are produced by
UAM. In the MMC the volume fraction of wire is relatively low, 0.77%, yet yields an
average increase in modulus of 8.9%.Mechanical Engineerin
