Thin
periodic structures
depend on two interrelated small geometric
parameters $\varepsilon$ and $h(\varepsilon)$ which control the thickness of constituents
and the cell of periodicity. We study homogenisation of elasticity theory
problems on these structures by method of asymptotic expansions.
A particular attention is paid to the case of
critical thickness when
$\lim_{\varepsilon\to 0} h(\varepsilon)\varepsilon^{-1}$ is a positive
constant.
Planar grids are taken as a model example.
