Imagine using unattended ground sensors to provide continuous weather reports and surveillance of critical targets in enemy areas. The Defense Department thinks the idea is sound enough to pursue. The agency includes it among nine projects it will fund this fiscal year under its Advanced Concept Technology Demonstration (ACTD) program. The other projects are: a networked early warning system for biological threats, a method for detecting coordinated attacks on computer networks, a "joint continuous strike environment" using combined suites of weapons on targets, a system for moving weapons and other materiel from ship to shore in heavy seas, an interface between major tactical data links on the ground and in the air, an advanced forward looking infrared system for precise target location and identification, a markedly improved capability for precise counterfire at the battle-theater level, and a line-of-sight system for high-speed destruction of many tanks at once.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry “to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].”
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
