Reference for DKT elements

Hello all,
Can someone please give me a reference that includes the formulation of DKT elements of code_aster and how it is coded? I could not find a good scientific reference in the user manual.
Thanks in advance.

Re: Reference for DKT elements

Thanks for your response Paster. I already saw the documentation you sent but I want some papers/books to be able to cite them in addition to code_aster manual. I cannot find some of the references in the manual when I search online. I asked here to see whether if someone knows a good paper/book that introduces the DKT formulations that code aster uses?

Re: Reference for DKT elements

Hello,

The original work :
J.L. Batoz, K.J. Bathe, L.W. Ho, A study of three-node triangular plate bending elements.
International Journal for Numerical Methods in Engineering, 15: 1771-1812, 1980.

For quad4:
J.L. Batoz, M. Ben Tahar, Evaluation of a new thin plate quadrilateral element. International
Journal for Numerical Methods in Engineering, 18: 1655-1678, 1982

It is very strange that these references are not in the documentation !

Thanks a lot, AsterO'dactyle. Can you please share the reference of the COQUE_3d elements as well? I cannot find the reference mentioned in U3.12.03 for these elements.
