Asymptotically Correct Dimensional Reduction of Nonlinear Material Models
(2018-07-30)
This work aims at dimensional reduction of nonlinear material models in an asymptotically accurate manner. The three-dimensional(3-D) nonlinear material models considered include isotropic, orthotropic and dielectric ...
Effect Of Cross-sectional Nonlinearities On Anisotropic Strip-based Mechanisms
(2013-05-28)
The goal of this work is to develop and demonstrate a comprehensive analysis of single and multi-body composite strip-beam systems using an asymptotically-correct geometrically nonlinear theory. The comprehensiveness ...
Inter-laminar Stresses In Composite Sandwich Panels Using Variational Asymptotic Method (VAM)
(2013-07-10)
In aerospace applications, use of laminates made of composite materials as face sheets in sandwich panels are on the rise. These composite laminates have low transverse shear and transverse normal moduli compared to the ...
Analysis of Thick Laminated Composite Beams using Variational Asymptotic Method
(2018-06-18)
An asymptotically-exact methodology is presented for obtaining the cross-sectional stiffness matrix of a pre-twisted, moderately-thick beam having rectangular cross sections and made of transversely isotropic material. The ...
Modeling of Contact in Orthotropic Materials using Variational Asymptotic Method
(2018-06-18)
Composites are materials which cater to the present and future needs of many demanding industries, such as aerospace, as they are weight-sensitive for a given requirement of strength and stiff ness, corrosion resistant, ...
Construction of 3D CAD Models From 2D Orthographic Views
(2011-01-19)
This thesis addresses the problem of constructing 3D CAD models from 2D engineering drawings of the object. Procedures for each step in the popular bottom-up approach are described. In each of the steps in this approach, ...
Studies On Bulk And Multilayer Composites Of Nb-Si Alloys
(2013-08-02)
The present thesis deals with Nb-Si alloy composites in both bulk and multilayer forms.
The work has been divided into two parts. First part (chapter 4-6) deals with Nb based
silicides binary and ternary alloys with ...
An Investigation On The Effect Of Structural And Microstructural Attributes On Magnetostriction Of Tb-Dy-Fe And Fe-Ga Alloys
(2016-04-26)
Giant magnetostrictive RFe2 type (R represents rare earths) intermetallics form an important class of magnetic materials keeping in view of their potential applications as sensors and/ or actuators. In this thesis, one ...
