**v6.02.133** SSNL133 — Elastic post-buckling of an L-structure
======================================================================

**Summary:**

An L-shaped structure composed of two slender beams of thin rectangular cross section is embedded at one end and subjected to force at the other end. We are looking for post-buckling behavior associated with positive strength values. The area of the test is:

• non-linear elastic mechanics (large displacements, large rotations),

• buckling of beams (instability),

• the models tested are POU_D_TGM, POU_D_T_GD, POU_D_TG,, POU_D_T, POU_D_E and POU_D_EM.

It allows you to test the kinematics in large movements and large rotations activated via the keyword GROT_GDEP.

Note: reference may be made to test case SSLL105 for a determination of the critical buckling loads for this structure.
