3. Modeling A#
3.1. Characteristics of modeling#
Two cases are treated:
in static, resolve with a STAT_NON_LINE. Taking into account the symmetry of the problem, the structure is maintained so as to maintain this symmetry.
in dynamics, resolution with a DYNA_NON_LINE. In this case no blocking is necessary.
Both cases should give the same results.
3.2. Tested sizes and results#
The final game for all the discreet, the reference is analytical:
