3. Modeling A

3.1. Characteristics of modeling

Discreet translational stiffness element

Characteristics of the elements

DISCRET:	with nodal masses	M_T_D_N
	and stiffness matrices	K_T_D_L
	and damping matrices	A_T_D_L

Boundary conditions:

in all nodes	DDL_IMPO =_F	(TOUT =” OUI “DY= 0., DZ= 0.)
at the end nodes		(GROUP_NO = AB DX= 0.)

Node names:

Point \(A\) = \(\mathrm{N1}\)	\({P}_{1}=\mathrm{N2}\)
Point \(B\) = \(\mathrm{N10}\)	\({P}_{2}=\mathrm{N3}\)
	\({P}_{8}=\mathrm{N9}\)

Modal recombination with all modes (8)	no time used	\(\mathrm{dt}=1.E–3s\)

Number of knots:	10
Number of meshes and types:	9 SEG2
