Abstract:
Korn's inequality is proved for an elastic body obtained by attaching to a plate several rods with clamped farther ends.
The thickness of the plate and the diameters of the rods are characterized
by a single small parameter $h$, which also gauges the distinctions
in the elastic properties of the elements of the junction.
The selection of the weighted anisotropic norms distinguishing the longitudinal
and transverse directions in the plate and in a rod ensures the asymptotic
accuracy of the inequality, which is substantiated by examples of particular
constructions. New results on single plates and rods are obtained
in the course of the proof.
