Abstract

The paper discusses the objectives, issues and research directions of the ONR program on active materials and adaptive structures. It addresses the mechanics tools necessary for the design of this new class of structures. The paper reviews the research in the mechanics of materials of high strain active materials and engineering active materials, hybrid active materials, constitutive modeling, failure of ferroelectric ceramics, and active material interaction with host material. Understanding failure mechanisms in active materials was recognized early in the program to be of great importance to reliable design of high performance actuators and their acceptance by the design community. New concept of engineering active materials, and developments of hybrid active materials are introduced, as means to achieve high performance actuation. The paper covers different design approaches for high strain/high frequency actuators and new actuator concepts and the mechanics of embedding of actuators in composite structures.
