Tensile wrinkling and creasing of an elastic half-space under a suction load
Roberta Springhetti, Davide Bigoni
A famous and thoroughly investigated instability set-up, susceptible to wrinkling and creasing, consists of an elastic half-space being prestressed under a dead load, applied at in…
Necking of thin-walled cylinders via bifurcation of incompressible nonlinear elastic solids
Roberta Springhetti, Gabriel Rossetto, Davide Bigoni
Necking localization under quasi-static uniaxial tension is experimentally observed in ductile thin-walled cylindrical tubes, made of soft polypropylene. Necking nucleates at multi…
Buckling of thin-walled cylinders from three dimensional nonlinear elasticity
Roberta Springhetti, Gabriel Rossetto, Davide Bigoni
The famous bifurcation analysis performed by Flügge on compressed thin-walled cylinders is based on a series of simplifying assumptions, which allow to obtain the bifurcation lands…
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…
