    Experimental and mumerical analysis of deformation of low-density thermally bonded nonwovens by Xiaonan Hou

    Published 2010
    “…Based on the experimental results obtained from tensile tests, continuous finite-element models were developed to simulate the material properties of the nonwoven material for its two principle directions: machine direction (MD) and cross direction (CD). Due to the continuous nature of the models, they were only used to establish the mechanical behaviour of the material by treating it as a two-component composite. …”
