Numerical Construction of Piecewise Virtual Fields
Research Output | Dar Al-hikmah Library | IIUM Only

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

Optimized Virtual Fields with Noise Minimization
Research Output | Dar Al-hikmah Library | IIUM Only

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

Structural Analysis of an Active Beam
Research Output | Dar Al-hikmah Library | IIUM Only

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

Buckling of Composite Perforated Plates
Research Output | Dar Al-hikmah Library | IIUM Only

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.

Mechanochemical Synthesis of Nanosized Hydroxyyapatite Powder and its Conversion to Dense Bodies
Research Output | Dar Al-hikmah Library | IIUM Only

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

Introduction of Piecewise Virtual Fields Method for Solution of Inverse Problems
Research Output | Dar Al-hikmah Library | IIUM Only

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

Quality Improvement of three-Way Catalytic Converter (Twc) System: Application of Failure Modes and Effects Analysis (Fmea) Methodology
Research Output | Dar Al-hikmah Library | IIUM Only

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

Numerical Model of Noise Effect in Full Field Data
Research Output | Dar Al-hikmah Library | IIUM Only

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

The Reciprocity Gap Method
Research Output | Dar Al-hikmah Library | IIUM Only

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
