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.
