A homogenization method for geometric nonlinear analysis of sandwich structures with initial imperfections
TLDR
In this article, a homogenization method for geometric nonlinear analysis of structural core sandwich panels is proposed, which provides high computational performance based on an efficient separation of scales and allows for description of buckling in these two scales and is shown to hold good accuracy with respect to equivalent 3D FEM models.About:

A review on non-classical continuum mechanics with applications in marine engineering
TL;DR: Marine structures are advanced material and structural assemblies that span over different length scales. The classical structural design approach is to separate these length scales as mentioned in this paper. But this approach is not suitable for many applications.
