Abstract
An engineered dispersed particle-cellular nanomatrix composite material is disclosed. The engineered dispersed particle-cellular nanomatrix composite material is configured for contact with a fluid and configured to provide a selectable and controllable transition from one of a first strength condition to a second strength condition that is lower than a functional strength threshold, or a first weight loss amount to a second weight loss amount that is greater than a weight loss limit, as a function of a time in contact with the fluid.
