Savage (www.savagearm.com) has introduced the AccuTrigger™, with trigger pulls adjustable from about 2.5 to 6 lbs in most 2004 centerfire hunting models and adjustable from about 1.5 to 6 lbs in the 12 Series Varmint and Law Enforcement Series. Most triggers today have heavy pulls to prevent accidental discharge; AccuTrigger allows shooters to set the trigger pull to their preference without paying a visit to a gunsmith. It also features AccuRelease™, which must be completely depressed to allow the rifle to discharge.
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.
