Tutorial: The dissipated energy pathfollowing solver
====================================================

This example is taken from the paper

E.Borjesson, J.J.C. Remmers, M. Fagerstrom (2022)          
A generalised path-following solver for robust analysis    
of material failure, Computational Mechanics

In section 3.1 a delamination buckling simulation is considered. The input file for
this cases can be found in the directory ''examples/solver/dissipatedEnergSolver''
The input file ''delam_buckling100.pro'' contains the input parameters for a simulation with 450
elements (400 finite strain continuum elements and 50 interface elements). The input file
''delam_buckling200.pro'' describes the same problem with 800 continuum and 50 interface elements.

These input files can be executed by typing::

  pyfem delam_buckling200.pro

The result load displacement curve will look as follows:
