## Contribution

It introduces a study of Young modulus and shear wave velocity in microcomposites of ferroelastic-dielectric type, combining theoretical and experimental approaches.

## Key findings

- Extended understanding of mechanical response in microcomposites
- Quantitative analysis of Young modulus and shear wave velocity
- Correlation between microstructure and mechanical properties

## Abstract

The problem of effective shear and bulk moduli, of an effective Poison's ratio and of an effective dielectric response in microcomposites of the ferroelastic-dielectric type was studied by us recently. Recently one of us, M. Hudak, studied static mechanical properties of the EVA material theoretically and experimentally. We extend our mentioned study of mechanical response of microcomposites of the type ferrolastics - dielectrics to study of Young modulus and shear wave velocity.
