Accurate Computational Algorithms For Hyperbolic Conservation Laws
(2010-10-08)
The numerics of hyperbolic conservation laws, e.g., the Euler equations of gas dynamics, shallow water equations and MHD equations, is non-trivial due to the convective terms being highly non-linear and equations being ...
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 ...
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 ...
Improved Numerical And Numeric-Analytic Schemes In Nonlinear Dynamics And Systems With Finite Rotations
(2010-04-13)
This thesis deals with different computational techniques related to some classes of nonlinear response regimes of engineering interest. The work is mainly divided into two parts. In the first part different numeric-analytic ...
Flow Over A Circular Cylinder With A Flexible Splitter Plate
(2010-07-08)
Previous work on rigid splitter plates in the wake of a bluff body has shown that the primary vortex shedding can be suppressed for sufficiently long splitter plates. In the present work, we study the problem of a flexible ...
