Finite element solution methods for linear and nonlinear beam-on-foundation problems
The objective of this research is to develop finite elements and iterative techniques for numerical solution of linear and nonlinear beam-on-foundation problems encountered in structural engineering. Although closed-form ...
Effects of axial forces on drillstring lateral vibrations
Lateral vibrations of stabilized bottomhole assemblies (BHA) of drill-strings often exhibit quite complicated patterns. Previous work has taken into account nonlinearities due to fluid damping, wall contact, eccentric ...
Development of an elastic solution for predicting the dynamic response of beams subjected to a moving mass
In this investigation, the problem of the response of beams subjected to a moving mass has been studied. The main objective in this thesis is to provide easy and acceptable solutions for this problem. Three different methods ...
Two-dimensional modeling of flow and sedimentation
A two-dimensional (vertical) flow model is developed to simulate open channel flow. The governing equations are solved without any depth averaging. Free surface movement is handled with the help of Arbitrary Lagrangian ...
