Instabilities in elastic accelerated solids
When a solid plate is accelerated by an external pressure 0 p an instability similar to the Rayleigh-Taylor one appears if the plate is not perfectly flat. Due to the elastoplastic properties of the material the growth of the instability is lower than in a pure fluid case. In a very simple interpretation, the pressure difference across the irregular surface provokes the instability that can be ...
متن کاملElastic heterogeneity of soft random solids
Spatial heterogeneity in the elastic properties of soft random solids is examined via a semi-microscopic model network using replica statistical mechanics. The elastic heterogeneity is characterized by random residual stress and Lamé coefficient fields, and the statistics of these quantities is inferred. Correlations involving the residual-stress field are found to be long ranged and governed b...
متن کاملSpherical indentation of elastic-plastic solids
The finite-element method is used to perform an accurate numerical study of the normal indentation of an elastic-plastic half-space by a rigid sphere. The effects of elasticity and strain-hardening rate of the half-space are explored, and the role of friction is assessed by analysing the limiting cases of frictionless contact and sticking friction. Indentation maps are constructed with axes of ...
متن کاملAthermal nonlinear elastic constants of amorphous solids.
We derive expressions for the lowest nonlinear elastic constants of amorphous solids in athermal conditions (up to third order), in terms of the interaction potential between the constituent particles. The effect of these constants cannot be disregarded when amorphous solids undergo instabilities such as plastic flow or fracture in the athermal limit; in such situations the elastic response inc...
متن کاملElastic properties of colloidal solids with disorder
— Recent progress in approaches to determine the elastic constants of solids starting from the microscopic particle interactions is reviewed. On the theoretical side, density functional theory approaches are discussed and compared to more classical ones using the actual pair potentials. On the experimental side, video microscopy has been introduced to measure the elastic constants in colloidal ...
