FINITE ELEMENT ANALYSIS OF THE DYNAMIC RESPONSE OF COMPOSITE PLATES WITH EMBEDDED SHAPE-MEMORY ALLOY FIBERS

摘要

Applications of SMA Nitinol fibers in the natural frequency analysis of composite plates have been successfully demonstrated. The fundamental equations governing the behavior of SMA fiber-reinforced multilayer composite plates have also been introduced in this work. The stress-strain relationships for a single composite layer with embedded SMA fibers has been presented. The finite element formulation to predict changes in natural frequencies and modes of vibration of composite laminates with SMA fibers has also been shown in the paper.
