v6.02.141 SSNL141 - Multifiber and multi-material beams

Summary:

The objective of this test is to validate the use of multi-material sections for multifibre beams.

The beam is made of two materials.

Two types of calculations are made:

• a static calculation

• two modal calculations, one with option MASS_MECA and the other with option MASS_MECA_DIAG

The reference solutions are based on Euler’s beam theory.
