The poker-chip experiments of synthetic elastomers
Farhad Kamarei, Aditya Kumar, Oscar Lopez-Pamies
In a recent study, Kumar and Lopez-Pamies (J. Mech. Phys. Solids 150: 104359, 2021) have provided a complete quantitative explanation of the famed poker-chip experiments of Gent an…
Cavitation in elastomers: A review of the evidence against elasticity
Evan Breedlove, Chao Chen, David Lindeman +1
In spite of the growing body of evidence against it, the elasticity view of the phenomenon of cavitation in elastomers continues to be utilized in numerous studies. In this context…
Abaqus implementation of a large family of finite viscoelasticity models
Victor Lefèvre, Fabio Sozio, Oscar Lopez-Pamies
In this paper, we introduce an Abaqus UMAT subroutine for a family of constitutive models for the viscoelastic response of isotropic elastomers of any compressibility -- including…
The nonlinear elastic response of bicontinuous rubber blends
Fabio Sozio, Francois Lallet, Antoine Perriot +1
Rubber blends are ubiquitous in countless technological applications. More often than not, rubber blends exhibit complex interpenetrating microstructures, which are thought to have…
Liquid Filled Elastomers: From Linearization to Elastic Enhancement
Juan Casado Dìaz, Gilles A. Francfort, Oscar Lopez-Pamies +1
Surface tension at cavity walls can play havoc with the mechanical properties of perforated soft solids when the cavities are filled with a fluid. This study is an investigation of…
The trousers fracture test for viscoelastic elastomers
Bhavesh Shrimali, Oscar Lopez-Pamies
Shrimali and Lopez-Pamies (2023) have recently shown that the Griffith criticality condition that governs crack growth in viscoelastic elastomers can be reduced to a fundamental fo…
The delayed fracture test for viscoelastic elastomers
Bhavesh Shrimali, Oscar Lopez-Pamies
In a recent contribution, Shrimali and Lopez-Pamies (2023) have shown that the Griffith criticality condition that governs crack growth in viscoelastic elastomers can be reduced --…
The "pure-shear" fracture test for viscoelastic elastomers and its revelation on Griffith fracture
Bhavesh Shrimali, Oscar Lopez-Pamies
Strikingly, "pure-shear" fracture tests have repeatedly shown that fracture nucleation in (common hydrocarbon and other types of) viscoelastic elastomers occurs at a critical stret…
Homogenization of elastomers filled with liquid inclusions: The small-deformation limit
Kamalendu Ghosh, Victor Lefevre, Oscar Lopez-Pamies
This paper presents the derivation of the homogenized equations that describe the macroscopic mechanical response of elastomers filled with liquid inclusions in the setting of smal…
Enhancement of elasto-dielectrics by homogenization of active charges
Gilles A. Francfort, Antoine Gloria, Oscar Lopez-Pamies
We investigate the PDE system resulting from even electromechanical coupling in elastomers. Assuming a periodic microstructure and a periodic distribution of micro-charges of a pre…
