Homogenization using experimental data

Submitted by Structrual Engineer on

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.

Problem Modeling JKR contact using Abaqus

Submitted by diorusso on

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. 

Overhead Electrical Conductors

Submitted by Alain Cardou on

I just discovered (thanks to Dr K.O. Papailiou) this interesting 2007 paper on helical strand mechanical modelling. It is an up-to-date (and apparently quite exhaustive, except for non-English language contributions) review on the subject by T. Manvel Raj and N.S. Parthasarathy, of India. Its title: “A Complete Review on Friction Models of Composite Cables”. It was published in a Russian Academy of Applied Mechanics and Sciences journal, the International Journal of Mechanics of Composite Materials and Constructions, Vol. 13, No 3, pp. 356-384. Here is the Abstract:
