Homogenization using experimental data

homogenization

constitutive eqations

I am exploring the area of homogenization applications in structural
engineering.

In the literature which I have studied so far, I found papers which
developed these techniques using the structural properties of the periodic
"Unit Cell".

I am interested in estimation of approximate homogeneous properties from the
experimental data of periodic/random structures.

Can someone comment on the feasibility of this study and point me to relevant
literature if available.

crack propagation analysis

JKR contact

Hello Everyone,

I have been working on solving contact problems relating to fibrillar adhesives over the past 3 yrs of my PhD work. In the past, I used Comsol FEM to model contact interactions by implementing the Dugdale-Barenblatt traction separation law at the contact interface.
