Multiscale Modelling of Textile Composites

Multiscale Modelling of Textile Composites

Composites materials have been rapidly developed and adopted since World War II accompanied by the emergence of new matrix materials and high-performance fibers. Modern aircraft and space structures comprise of 50 to 70 percent of this unique blend of composite materials due to their ultra-low weight and high toughness. Robust predictions of the thermo-mechanical response of anisotropic composite materials across the different length scales are of the utmost importance to improve the efficiency of composite structures and to develop an in-depth understanding of microstructure-property relations.

Our current activities are focused on

  • Development of a generic and efficient framework for multiscale modelling and failure prediction of fabric reinforced composites under static and impact loadings.
  • The real phenomenon that occurs at the micro level of the composite is simulated via representative volume element.
  • Various techniques used for the analysis are
    • Modified classical laminate theory
    • Semi-analytical homogenization schemes
    • Mechanics of structure genome
    • Finite element analysis with embedded cohesive zone modelling.
  • The characteristics obtained at lower scales are then implemented within macroscopic models for optimization of the large-scale composite structures.
