Abstract

Mixed numerical-experimental techniques for the characterisation of anisotropic solids through their vibrational behaviour: a review W. P. De Wilde Vrije Universiteit Brussel, Department of Mechanics of Materials and Constructions, Faculty of Engineering, Belgium Abstract The identification of the stiffness properties of composite materials structural components is seriously hampered by the anisotropy of the material properties. Their anisotropic nature requires the determination of different independent engineering constants like Young's moduli, shear moduli, Poisson's ratios and other coupling coefficients. Traditional experimental tests are cumbersome, time consuming and most of all inadequate. In view of solving these problems, many authors have tried to develop mixed numerical/experimental methods. Some of them are based on the observation and modelling of their vibrational behaviour. The author wants to show what the characteristics of these methods are, their potent
