3.4. notes#

In the results table, we reported the frequencies whose modes are identical to the reference modes.

  • the effects of transverse shear are overlooked in modeling DKT,

  • Code_Aster results are much higher than the reference results,

  • appearance of a membrane mode between modes 2 and 3 and between modes 5 and 6 of reference.
