ABSTRACT

Textiles are fiber-based structures. The modern textile reinforcement composites are based on fiber-based structures, too. The modeling of these structures was based early mainly on geometrical methods or using simple models based on the analytical mechanics. During the last time significant results are achieved using the computational mechanics. The most problems during modeling are in the combination of the following typical parameters of the structures:

- they are based on a huge number of single fibers (at least 40 fibers per cross section in a single yarn, 50 000 filaments in carbon tow, couple hundred yarn pieces per small sample)

- fibers and their parameters are not regular

- friction (with the stick and slip effect) plays significant role for the behavior

- the problems are usually non-linear (non-linear geometry, non-linear relations in the equilibrium equations) and the systems of equations are usually stiff.

- properties of the structures depend on the load case (under tension, lateral compression, torsion, bending)

- the interaction between the textile and the matrix in a composite materials is very complex.



The goal of the symposium will be to connect the peoples, using computational mechanics to model the fiber–bases structures and the problems of their engineering design. Further the goal is to demonstrate the open problems to the peoples of the computational mechanics and to allow broad discussions and possibilities for new cooperation between research teams
