Models for the elastic deformation of honeycombs
A theoretical model has been developed for predicting the elastic constants of honeycombs based on the deformation of the honeycomb cells by hexme, stretching and hinging. This is an extension ofExpand
Surface roughness analysis, modelling and prediction in selective laser melting
Abstract Selective Laser Melting (SLM) is an increasingly employed additive manufacturing process for the production of medical, aerospace, and automotive parts. Despite progresses in materialExpand
Auxetic behavior from rotating squares
Auxetic materials exhibit the very unusual properties of becoming wider when stretched and narrower when squashed [1], that is they have negative Poisson’s ratios. Apart from the pure scientificExpand
The manufacture and characterisation of a novel, low modulus, negative Poisson’s ratio composite
Abstract Relatively few negative Poisson’s ratio (auxetic) composites have been manufactured and characterised and none with inherently auxetic phases [Milton G. J. Mech. Phys. SolidsExpand
ElAM: A computer program for the analysis and representation of anisotropic elastic properties
The ElAM (Elastic Anisotropy Measures) code carries out the required tensorial operations and creates 3D models of an elastic property's anisotography, and can also produce 2D cuts in any given plane and query a database of elastic constants to support meta-analyses. Expand
A new approach to the design and optimisation of support structures in additive manufacturing
Support structures are required in several additive manufacturing (AM) processes to sustain overhanging parts, in particular for the production of metal components. Supports are typically hollow orExpand
Elastic constants of 3-, 4- and 6-connected chiral and anti-chiral honeycombs subject to uniaxial in-plane loading
Finite Element models are developed for the in-plane linear elastic constants of a family of honeycombs comprising arrays of cylinders connected by ligaments. Honeycombs having cylinders with 3, 4Expand
Microporous materials with negative Poisson's ratios. I. Microstructure and mechanical properties
A microporous, anisotropic form of expanded polytetrafluoroethylene has been found to have a large negative major Poisson's ratio. The value of Poisson's ratio varies with tensile strain and canExpand
Auxetic polymers: a new range of materials
Abstract Materials with a negative Poisson's ratio (auxetic materials) have the fascinating property of becoming fatter when stretched. This article describes some of the consequences of thisExpand
