Multiscale Expansions for Linear Clamped Elliptic Shells
We investigate solutions of the two-dimensional Koiter model and of the three-dimensional linear shell model in the case where the shell is clamped and its mean... -
An effective model for critically wrinkled arches
Within the framework of the Koiter's linear elastic shell theory, we study the limit model of a plane arch whose mid-surface is periodically waved.The magnitude and... -
