**v3.01.103** SSLL103 - Elastic buckling of an angle iron
============================================================

**Summary:**

A biarticulated straight beam (angle with equal wings) is subjected to a normal force (eccentric or not) or to a bending moment.

We are looking for the critical loads of elastic buckling.

• linear elastic mechanics,

• buckling of a beam,

• eccentricity of the center of torsion,

• interest of the test: calculation of the geometric rigidity matrix of elements POU_D_TG and POU_D_T,

• 2 models.

Uncertainty persists on the number of buckling modes of the reference solution [:ref:`§5 <§5>`].
