Automated modeling for complex woven mesostructures

Computational methods for modeling complex three-dimensional woven structur es are reviewed and software tools for automated model construction are des cribed. The tools make use of image processing, geometric and attribute mod eling, automated discretization, and efficient solvers. The discretization techniques control mesh periodicity and volume fraction errors of meshed co nstituents due to approximation of curved boundaries. Numerical examples fo r several woven structures are demonstrated in the context of linear elasti city. (C) 1999 Elsevier Science S.A. All rights reserved.
