D. Caillerie et E. Sanchezpalencia, ELASTIC THIN SHELLS - ASYMPTOTIC THEORY IN THE ANISOTROPIC AND HETEROGENEOUS CASES, Mathematical models and methods in applied sciences, 5(4), 1995, pp. 473-496
Asymptotic (two-scale) methods are used to derive thin shell theory fr
om three-dimensional elasticity. The asymptotic process is done direct
ly for the variational formulations, and existence and uniqueness theo
rems are given for the shell problem. The asymptotic behavior is the s
ame as that recently derived by the authors using classical hypotheses
of shell theory. The role of the subspace G of pure bendings (inexten
sional motions) appears in a natural way. The asymptotic is basically
described by a leading older term contained in G and a lower order ter
m contained in the orthogonal to G. As in anisotropic heterogeneous pl
ates, which exhibit a coupling between flexion and traction, in hetero
geneous shells there is coupling between the terms in G and in its ort
hogonal.
