Development of an expert system for evaluation of the strength of matrix shape memory composites

摘要

In this paper, a study on the development of an expert system for an Al matrix composite with shape memory alloy fiber was performed to evaluate the thermo-mechanical behavior and the mechanical properties for the composite. An expert system is a useful computer-based analysis system designed to establish the analysis technique of composites fabricated under various conditions. This system developed allows prediction of thermo-mechanical behavior and mechanical properties for other composite with shape memory alloy fiber. For finite element analysis, an analytical model is assumed as two-dimensional axi-symmetric model of one fiber and the matrix. In addition, the FEA was carried out at two critical temperature conditions; room temperature and high temperature (363 K). The finite element analysis result was compared with the test result for the analysis validity.
