This chapter discusses virtual fields method which is used for characterization of composite or anisotropic material with the use of full field heterogeneous deformation data. The method has shown very promising results when used for identification of materials constitutive properties and a set of full field data. This chapter discusses the basic w

Lateral crushing experiment on a model of a composite based-fuselage of Unmanned Aerial Vehicle (UAV) has been carried out. The middle cylindrical part of the fueslage was selected as the area of interest. The model was fabricated using Carbon fiber/epoxy by means of hand lay-up method and was put under quasi-static compression loading in order to

This chapter discusses the numerical issues in construction of piecewise virtual fields over a specimen. The improvement and advantages over the use of single virtual element has been examined. Such a piecewise construction has been successfully used to characterize a thin composite plate in bending. Moreover, the use of piecewise elements has show

This chapter discusses numerical issues in noise minimization and a representative cost function to be minimized. Such a minimization helps in finding a unique and optimized set of unknown bending rigidity that is least sensitive to noise. This chapter presents an optimized identification procedure with minimum noise sensitivity and its adaption fo

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
