3. Modeling A

3.1. Characteristics of modeling

Shell element DKT (quarter plate modeling)

Number of layers: COQUE_NCOU = 3

Boundary conditions:	DDL_IMPO
at all the nodes of the arc ABC	(GROUP_NO = “ABC”, DX= 0. , DY= 0. , DZ= 0.) DRX =0. , DRY =0. , DRZ =0.)
at all nodes in the segment] OA [	(GROUP_NO = “OA”, DY= 0. , DRX =0. , DRZ =0.)
at all the nodes in the segment] OC [	(GROUP_NO = “OC”, DX= 0. , DRY =0. , DRZ =0.)
to node O	(GROUP_NO = “O”, DX= 0. , DY= 0. , DRX =0. , DRY =0. , DRZ =0.)

Point O	meshes: M30, M33
Point A	meshes: M76
Point B	meshes: M39, M40, M51
Point C	meshes: M1
Point D	meshes: M55, M56, M65
Point E	meshes: M8, M17, M18
Point F	meshes: M34, M35, M35, M37, M41, M46, M47, M48

3.2. Characteristics of the mesh

Number of knots: 50

Number of meshes and types: 76 TRIA3

We also test:

• the continuity of fields EPSI_ELGA and EPSI_ELNO between layers (non-regression tests). In fact, the value calculated at level SUP of the N layer is equal to the value calculated at the INF level of the COUCHE N+1,

• the volume distribution of component SIYY (non-regression tests) of fields SIEF_ELGA and SIGM_ELNO as well as the volume of the circular plate.
