Examination of Advanced Solution Strategies for Nonlinear FE Analysis
Dissertation submitted as part requirement for the Degree of Master of Science in Structural Engineering By Wael Darwich
The University of Sheffield
Department of Civil and Structural Engineering This dissertation examines advanced solution strategies for tracing the nonlinear loaddisplacement behaviour of engineering structures, using Newtonlike, arclength techniques (first developed by Riks), and line search methods. Only material nonlinearity is studied; first using a simple nonlinear constitutive relationship, and then a more advanced one based on the Hashiguchi subloading surface plasticity model for soil. A series of MATLAB scripts are developed to illustrate the above techniqes and to solve some examples (using just one 3D Finite Element) which indicate the effects of path dependency on the results.
