2. Benchmark solutions#
2.1. Calculation method#
The reference solution is calculated with Code_Aster using the « classical » Newton-Raphson algorithm.
2.2. Reference quantities and results#
The reference result is the force-displacement curve obtained with the iterative Newton-Raphson method. Force values are compared at different loading levels.
2.3. Uncertainty about the solution#
Comparison of two solutions obtained with Code_Aster. Since method IMPLEX is by definition approximate, we will have a deviation from the Newton solution (but which must remain small).
