An adaptive beam model of anisotropically actuated beam is formulated to determine the displacement and twist actuation capabilities of anisotropic piezoelectric actuators as related to the potential application for the helicopter blade control. The chosen beam has been modeled in ANSYS. Some existing results on piezoeletric actuators with differen

The buckling behaviour of homogeneous and composite plates with cutouts under axial compression is investigated numerically by using ANSYS software. The influence of material orientation and the length to width ratio on the buckling response of the plates is examined.

In this work, nanosized hydroxyapatite (HA) powder was synthesized via mechanochemical method by a dry mixture of calcium hydroxide Ca(OH)2 and di-ammonium hydrogen phosphate (NH4)2HPO4 powders. The effect of mechanochemical process on powder properties was investigated. Three rotation speeds of 170 rpm, 270 rpm and 370 rpm were chose with 15 hours

This chapter discusses the direct identification of bending rigidities of a thin anisotropic composite plate. The simultaneous identification of constitutive parameters from heterogeneous strain fields is an important issue in the experimental solid mechanics community.The idea is to determine the unknown parameters from a single test giving a uniq

This book intends to present the application of FMEA method on Three-Way Catalytic Converter (TWC) system. Catalytic converter of auto-exhaust emission is one of the most successful applications of heterogeneous catalysis, both in commercial and environmental point of view. Catalytic converter has been proved critical to controlling pollution of CO

This chapter discusses the important issue of experimental noise simulation in the formulation of piecewise virtual fields method for the characterization of thin composite plate. In actual practice, the full field data captured through an optical dive on the surface of a specimen is always prone to some noise effect. In order to accurately identif

This chapter discusses reciprocity gap method that makes use of full filed data. In this method, full field displacement data is measured at the specimen boundary. For the case of static loading, displacement-force boundary data is measured and using principle of virtual work, a reciprocity gap functional is reconstructed to give the interior and w

This chapter discusses constitutive equation gap method used for identification of materials constitutive parameters. It involves a comparison of given stress field and displacement field to a computed stress field generated by using an initial set of materials constitutive model. This method is based on the gap estimation and minimization that is

This chapter discusses the equilibrium gap method that utilizes full field data measured over a surface. The method has been shown to give promising results for identification of elastic constitutive properties. Also, the method has been applied to the case of a damaged specimen. Initial trial values of unknown data is given as input and then the g
