Liquid Structures: a novel Computational Fluid Dynamics (CFD) inspired metamaterial
Paolo Gallina, Massimiliano Gei, Lorenzo Scalera +1
We present a theoretical framework for new structural metamaterials we refer to as liquid structures: a topology of bistable mechanisms made up of a high number of cells that are s…
Experimental investigation of progressive instability and collapse of no-tension brickwork pillars
Massimiliano Gei, Diego Misseroni
The progressive instability behaviour of compressed dry-stone rectangular pillars loaded with an eccentric load is assessed experimentally and compared with the theory. Photoelasti…
Optimisation of hierarchical dielectric elastomer laminated composites
Massimiliano Gei, Kudzai C. K. Mutasa
This paper is concerned with the optimisation of the actuation response of electro-elastic, rank-two laminates obtained laminating a core rank-one composite with a soft phase which…
Progressive instability in circular masonry columns
M. Broseghini, P. Zanetti, A. D. Jefferson +1
The instability behaviour of eccentrically loaded circular masonry columns is investigated. Two approaches are considered for the analysis. One is based on a semi-analytical formul…
Analysis of viscoelastic soft dielectric elastomer generators operating in an electrical circuit
Eliana Bortot, Ralf Denzer, Andreas Menzel +1
A predicting model for soft Dielectric Elastomer Generators (DEGs) must consider a realistic model of the electromechanical behaviour of the elastomer filling, the variable capacit…
Experimental investigation of the elastoplastic response of aluminum silicate spray dried powder during cold compaction
F. Bosi, A. Piccolroaz, M. Gei +3
Mechanical experiments have been designed and performed to investigate the elasto-plastic behaviour of green bodies formed from an aluminum silicate spray dried powder used for til…
Optimal energy-harvesting cycles for load-driven dielectric generators in plane strain
R. Springhetti, E. Bortot, G. deBotton +1
The performances of energy harvesting generators based on dielectric elastomers are investigated. The configuration is of a thin dielectric film coated by stretchable electrodes at…
Performance of soft dielectric laminated composites
Massimiliano Gei, Roberta Springhetti, Eliana Bortot
This paper contains a thorough investigation of the performance of electrically activated layered soft dielectric composite actuators under plane deformation. Noting that the activ…
The role of electrostriction on the stability of dielectric elastomer actuators
M. Gei, S. Colonnelli, R. Springhetti
In the field of soft dielectric elastomers, the notion electrostriction indicates the dependency of the permittivity on strain. The present paper is aimed at investigating the effe…
The Rayleigh-Lamb wave propagation in dielectric elastomer layers subjected to large deformations
Gal Shmuel, Massimiliano Gei, Gal deBotton
The propagation of waves in soft dielectric elastomer layers is investigated. To this end incremental motions superimposed on homogeneous finite deformations induced by bias electr…
