Finite Element Analysis of the Ramberg-Osgood Bar

- D. Wei, M. Elgindi
- Mathematics
- 14 August 2013

In this work, we present a priori error estimates of finite element approximations of the solution for the equilibrium equation of an axially loaded Ramberg-Osgood bar. The existence and uniqueness… Expand

On the numerical solution of perturbed bifurcation problems

- M. Elgindi, R. Langer
- Mathematics
- 1995

Some numerical schemes, baseduponNewton's and chord methods, for thecomputations of the perturbed bifurcation points as well as the solution curves through them, are presented. The "initial" guesses… Expand

A Note on the Proof of the Perron-Frobenius Theorem

- Yun Cheng, Timothy Carson, M. Elgindi
- Mathematics
- 7 November 2012

This paper provides a simple proof for the Perron-Frobenius theorem concerned with positive matrices using a homotopy technique. By analyzing the behaviour of the eigenvalues of a family of positive… Expand
