EB21

2D Elastic Bernoulli Beam

  • Number of Nodes: 2

  • Number of DoFs: 3 (Translation, Translation, Rotation)

Syntax

element EB21 (1) (2) (3) (4) (5) (6) [7]
# (1) int, unique element tag
# (2) int, node i
# (3) int, node j
# (4) double, area
# (5) double, moment inertia
# (6) int, material tag
# [7] bool string, nonlinear geometry switch, default: false

Remarks

  1. No matter what material model is used, only the initial stiffness is used for computation since EB21 is an elastic beam element.

  2. Unlike 3D beam elements, there is no need to attach an orientation to 2D beam elements.
