Buckling of an Epithelium Growing under Spherical Confinement
bioRxiv, 2019 Many organs, such as the gut or the spine are formed through folding of an epithelium. This change in shape is usually attributed to tissue heterogeneities, for example, local apical contraction.

Experimental Investigation and Analysis of Dynamic Buckling of Drill String in Horizontal Well
Shock and Vibration, 2017 Buckling of tubulars has been the subject of many researches in the past. However, the models in previous research always followed the same assumptions: the friction and rotation effects are ignored.

Fabrication‐Directed Entanglement for Designing Chiral and Anisotropic Metamaterial Foams
Advanced Engineering Materials, EarlyView.This work introduces fabrication‐directed entanglement (FDE), combining viscous thread printing and topology optimization to program entangled foams with spatially patterned stiffness. By tuning coil density, FDE enables anisotropy, programmable Poisson's ratio, and chirality in foams.

Effects of introducing dynamic constraints for buckling to truss sizing optimization problems [PDF]
FME Transactions, 2018 In this paper the effects of adding buckling constraints to truss sizing optimization for minimizing mass are investigated. Introduction of buckling testing increases the complexity of the optimization process as Euler buckling criteria changes with each
