Material and Failure Models for Textile Composites

摘要: The complex three-dimensional structure of textile composites makes the experimental determination material parameters very difficult. Not only number constants increases, but especially through-thickness are hardly quantifiable. Therefore an information-passing multiscale approach for computation is presented as enhancement tests, also alternative to tests. consists three scales and includes unit cells on micro- mesoscale. With micromechanical cell stiffnesses strengths unidirectional fiber bundle can be determined. mesomechanical describes architecture composite provides computations macroscale. By comparison test data results numerical analysis models validated.
