摘要: An experimental technique for evaluating the elastic properties of functionally graded materials (FGMs) is proposed. Ultrasonic pulse-echo measurements in conjunction with impact testing permit determination Young's modulus, Poisson's ratio, and mass density material its longitudinal variation. The details formulation implementation issues are discussed this paper. These techniques have been applied successfully to evaluate a model material.
