Global instabilities of pyramidal trusses

Trends in Computational and Applied Mathematics
This paper presents an exact analytical study of global instabilities in pyramidal trusses under large displacements. Using the stationarity of total potential energy and Green-Lagrange strain, non-linear equilibrium equations are derived for a 3-bar ...

The Effect of Graphene on the Fatigue Response and Failure Mechanism of Composite Materials: A Review

Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 3, Page 933-962, March 2026.
ABSTRACT This review investigates the influence of graphene on the fatigue performance of polymer‐based composites, focusing on both unreinforced matrices and fiber‐reinforced composite laminates. Graphene materials, including nanoplatelets, graphene oxide, and hybrid nanostructures, offer exceptional mechanical, electrical, and barrier properties that

Physical Intelligence in Small‐Scale Robots and Machines

Advanced Materials, Volume 38, Issue 12, 25 February 2026.
“Physical intelligence” (PI) empowers biological organisms and artificial machines, especially at the small scales, to perceive, adapt, and even reshape their complex, dynamic, and unstructured operation environments. This review summarizes recent milestones and future directions of PI in small‐scale robots and machines.

Morphoelastic rods Part 1: A single growing elastic rod [PDF]

, 2012
A theory for the dynamics and statics of growing elastic rods is presented. First, a single growing rod is considered and the formalism of three-dimensional multiplicative decomposition of morphoelasticity is used to describe the bulk growth of Kirchhoff

Pattern Transitions in a Soft Cylindrical Shell

, 2018
Instability patterns of rolling up a sleeve appear more intricate than the ones of walking over a rug on floor, both characterized as uniaxially compressed soft-film/stiff-substrate systems. This can be explained by curvature effects.

Hilltop buckling as the A and O in sensitivity analysis of the initial postbuckling behavior of elastic structures

Journal of Civil Engineering and Management, 2009
The coincidence of a bifurcation point with a snap‐through point is called hilltop buckling. In this paper, it either serves as the starting point ‐ the ?
