Investigation On Flexural Vibrations Of Bolted Laminates
(2013-07-02)
Bolted cores made of coated silicon steel sheets constitute a vital part of heavy electrical equipment for transformers, motors and turbogenerators. Bolted laminates are eminently suitable for facilitating smooth magnetic ...
Periodically Perforated Sheets : Design And analysis
(2013-06-17)
Periodically perforated sheets(PS) are ubiquitous in nature as well as in engineered artifacts developed for aerospace, automotive, marine, nuclear and structural applications. PS are indispensable for saving weight and ...
Contact Mechanics Of Layered Structures
(2009-06-30)
Contact mechanical study of layered structures is useful to various fields of
engineering, such as - mechanical engineering, civil engineering, materials engineering and biomechanics. Thin hard film coating on a compliant ...
A Comparative Study Of Different Numerical Techniques Used For Solving Incompressible Fluid Flow Problems
(2010-06-03)
Past studies (primarily on steady state problems) that have compared the penalty and the velocity-pressure finite element formulations on a variety of problems have concluded that both methods yield solutions of comparable ...
Towards Measurement And Simulation Of Elasto-Plastic Deformation
(2009-03-09)
The stretch forming process is frequently used in the automotive industry (outer pan-
els, inner panels, stiffeners etc.), the packaging industry and household appliances
sector, to manufacture complicated shapes and ...
Experimental And Finite Element Study Of Elastic-Plastic Indentation Of Rough Surfaces
(2009-06-24)
Most of the surfaces have roughness down to atomic scales. When two surfaces come into contact, the nature of the roughness determines the properties like friction and wear. Analysis of the rough surface contacts is always ...
Constraint Effects On Stationary Crack Tip Fields In Ductile Single Crystals
(2011-03-15)
In order to understand and predict the fracture behaviour of polycrystalline materials from a fundamental perspective, it is important to first investigate plastic deformation at a crack tip in a ductile single crystal. ...
Experimental And Theoretical Studies In Fatigue Damage Modeling
(2010-12-07)
This thesis has two parts.
In the first part, we use the results of new fatigue experiments conducted with variable load levels as well as variable stress ratios to critically assess three (two old and one relatively ...
