2. Benchmark solution

This solution [bib4] is the one obtained with the SAMCEF [bib1] software. The modeling is based on a shell theory in resultant efforts with a co-rotational formulation [bib3] and a discretization DSQ [bib2].

The mesh considered is

quadrilateral elements.

Newton’s strategy with imposed force level illustrates a difficulty of convergence. We push the calculation up to

.
