The material parameters for computational modeling of long-fibre composites with textile

Application of Acoustic Emission Analysis for Damage Investigations in Fibre and Textile Reinforced Composites

For the verification of pertinent failure and damage models of fibre and textile reinforced composites a clear identification of the particular damage entities is an essential premise. In such fibrous composites, the characteristic failure mechanisms are initiated on the microscale and result in a spontaneous release of elastic energy in terms of mechanical stress waves, the so-called acoustic ...

Models for Textile Composites Forming

INTRODUCTION Drape of dry fabrics or prepregs was recognised as an important feature in composites forming operations from the start. In the 1950s the first mathematical models were developed based on purely kinematic arguments. The assumption of zero fibre strains and trellis deformations led to the socalled fishnet approach. Typically, these methods require certain arbitrary constraints to re...

Computational modeling of multicellular constructs with the material point method.

Computational modeling of the mechanics of cells and multicellular constructs with standard numerical discretization techniques such as the finite element (FE) method is complicated by the complex geometry, material properties and boundary conditions that are associated with such systems. The objectives of this research were to apply the material point method (MPM), a meshless method, to the mo...

Approach of the Constitutive Material Behaviour of Textile Composites through Simulation

A complete approach for the determination of the complex constitutive behaviour of textile composites through finite element simulation is presented in this paper. In this work, simulations of different loading cases are carried out on small samples of textile composites, taking into account all individual fibers of the fabric and interactions taking place between them. The most delicate issue ...
