Damage identification in skeletal structures: A dynamic stiffness approach
(The University of Waikato, 2017)The present work is devoted to investigate ways of identifying cracks in skeletal structures by frequency monitoring. This is a challenging problem as the number of cracks, their severity and location all need to be found. ... -
Development of Elastomeric Composites from Iron Sand and Natural Rubber for Vibration Damping
(University of Waikato, 2015)Material with high damping capability is used to reduce vibration in structures. Magnetorheological elastomers (MREs) are a new group of damping materials which consist of an elastomeric matrix containing a suspension of ... -
Free vibration analysis of plates and shells by using the Superposition Method
(University of Waikato, 2010)This thesis is devoted to investigate the capability of the Superposition Method for obtaining the transient response of plates and the natural frequencies of thin doubly curved shallow shells. The Superposition Method ... -
Investigation into low power active electromagnetic damping for automotive applications
(University of Waikato, 2015)Automobile suspension systems carry out two important functions; road handling and passenger comfort. Hydraulic passive dampers are the most common system employed on vehicles, yet it is well known that passive suspension ... -
Modelling Buckling and Post-buckling Behaviours of Corrugated Paperboard Structures
(University of Waikato, 2012)The buckling and post-buckling behaviours of corrugated paperboard packaging structures are the focus of this study. The motivations for this study are to improve understanding of post-buckling behaviour to better predict ... -
Seismic isolation of buildings for vertical earthquake excitations
(The University of Waikato, 2022)This thesis concerns a seismic isolation mechanism for vertical component of earthquake. The vertical component of earthquake can be stronger and more destructive than the horizontal component in near-fault areas, for ... -
The Effect of Powder Characteristics and Processing Conditions on the Microstructure and Mechanical Properties of Titanium Alloys Made by Powder Forging
(University of Waikato, 2013)Powder compact forging was used to produce Ti and Ti-6Al-4V rocker arms using pre-alloyed and blended elemental powders. Green powder compacts with high relative density were manufactured by warm compaction. Due to the ... -
The use of positive and negative penalty functions in solving constrained optimization problems and partial differential equations
(The University of Waikato, 2009)The Rayleigh-Ritz Method together with the Penalty Function Method is used to investigate the use of different types of penalty parameters. The use of artificial springs as penalty parameters is a very well established ... -
Variable stiffness of metamaterial composite structure
(The University of Waikato, 2022)In recent years, numerous researchers have studied metamaterials because of their extraordinary mechanical properties that other materials do not possess. The concept of metamaterials has been widely introduced into the ...
