Postbuckling behavior of graphite-epoxy panels [PDF]
, 1984 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 ...

Adaptive Twisting Metamaterials
Advanced Materials, EarlyView.This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

Some comments on global-local analyses [PDF]
The main theme concerns methods that may be classified as global (approximate) and local (exact). Some specific applications of these methods are found in: fracture and fatigue analysis of structures with 3-D surface flaws; large-deformation, post ...

Advanced Materials Interfaces, EarlyView.PEDOT:PSS‐coated 3DP microstructures are introduced to realize TENGs with enhanced mechanical compliance and high electrical performance. Among the investigated geometries, arch‐shaped microstructures exhibit superior fatigue resistance due to their spring‐like behavior, enabling efficient stress distribution, stable contact evolution, and sustained ...

Shear buckling of square perforated plates [PDF]
The behavior of thin square perforated plates under the action of uniform shear deformation is studied experimentally and analytically using finite element analysis. Elastic Shear buckling strength is established as a function of the diameter of a round,
