4. B modeling#
4.1. Characteristics of modeling#
3 elements \(\mathrm{1D}\) (SEG2). Modeling BARRE
In this modeling, we duplicated the second calculation with STAT_NON_LINE in order to leave the elastic zone and thus be able to validate the anelastic deformations (EPSP_ELGA) in addition to the validation of the options EPVC_ELGA and EPME_ELGA on the elements BARRE on the elements carried out on the elastic calculation.
To achieve this aim, the cross section of the bar and the non-linearity parameters of the material were modified. The section changes to an area of \(1.5\) and the work hardening parameters are as follows:
D_ SIGM_EPSI = \(180\)
SY = \(100.\)
4.2. Characteristics of the mesh#
Number of knots: 6
Number of stitches: 3 SEG2
4.3. Tested sizes and results#
