Application of SFEM to SHM: Efficient Damage Detection Techniques,In this chapter the damage model derived in Chapter 9 will be used to develop numerical algorithms for damage detection studies. This chapter will present four such algorithms, namely, spectral power flow, the damage force indicator, genetic algorithms and the artificial neural network (ANN).

Introduction,y loading. Low frequency problems are categorized as . problems while those involving high frequency loading fall into the category of . problems. In structural dynamics problems, the frequency content of the dynamic load is of the order of a few hundred hertz (Hz) and the designer will be mostly in

Introduction to the Theory of Anisotropic and Inhomogeneous Materials,. Also, a brief introduction is given to smart composites and the basic constitutive models for composites, where a few standard smart materials can be embedded. Towards the end of the chapter a brief description of how to obtain constitutive models for inhomogeneous materials, such as functionally

Idealization of Wave Propagation and Solution Techniques,f wavenumbers and wave amplitudes. An .th-order differential equation will yield an .th-order characteristic equation for the wavenumbers, which are normally difficult to solve. Here, we adopt some traditional techniques based on the theory of linear algebra to solve for wavenumbers and wave amplitu
