Approximate Stability Analysis of Omega‐Stringer Stiffened Composite Panels
ABSTRACT Thin‐walled composite structures are widely used in weight‐critical applications such as aircraft and spacecraft. However, ensuring the stability of such structures under various load cases remains a key challenge in their design and optimization.

Buckling and postbuckling behaviour of gabled frames
With the continuing trend toward optimization of engineering structures it can be expected that buckling, and in particular imperfection sensitive forms of buckling, will increasingly govern design. This study investigates the buckling and postbuckling behaviour of planar steel gabled frames under static loading.

Postbuckling behavior of graphite-epoxy panels [PDF]
Structurally efficient fuselage panels are often designed to allow buckling to occur at applied loads below ultimate. Interest in applying graphite-epoxy materials to fuselage primary structure led to several studies of the post-buckling behavior of ...

ABSTRACT The structural design optimization aims for robust structures with minimal use of material resources, leading to slender and thin‐walled structures, which entail a higher risk of stability problems. This issue is further influenced by geometrical imperfections, which are subjected to uncertainties.

Architected Lattices with a Topological Transition
This article develops topological metamaterials showing multidirectional two‐step deformation under compression by embedding contact‐enabled topological mechanisms into lattice structures. Experiments on 3D‐printed 2D and 3D lattices and finite element simulations are conducted to demonstrate the working principle of the topological metamaterials.

ABSTRACT The structural properties of mechanical metamaterials are typically studied with two‐scale methods based on computational homogenization. Because such materials have a complex microstructure, enriched schemes such as second‐order computational homogenization are required to fully capture their nonlinear behavior, which arises from nonlocal ...
