A polymorphic element formulation towards multiscale modelling of composite structures

Multiscale modelling of the structural integrity of composite materials.

Multiscale Approach to Damage Analysis of Laminated Composite Structures

The presented work depicts results of a two-scale approach to the problem of damage and failure prediction on laminated composite structures. Modeling on the micro-level has enabled insight into the underlying physical processes which lead to homogenized properties of the macro-scale material. In this work, micromechanical analysis has been performed by application of the High Fidelity Generali...

A micromechanics-enhanced finite element formulation for modelling heterogeneous materials

In the analysis of composite materials with heterogeneous microstructures, full resolution of the heterogeneities using classical numerical approaches can be computationally prohibitive. This paper presents a micromechanics-enhanced finite element formulation that accurately captures the mechanical behaviour of heterogeneous materials in a computationally efficient manner. The strategy exploits...

Towards A Generic Supporting Environment For Multiscale Modelling

Multiscale modelling as an emerging modelling paradigm is now widely regarded as a promising and powerful tool in various disciplines. However, a multiscale model is usually much more difficult to develop than a single-scale model due to a range of challenges. This work presents a methodology to facilitate the development of multiscale models, which comprises three main modelling steps, namely ...

Multiscale Surrogate Modeling and Uncertainty Quantification for Periodic Composite Structures

Computational modeling of the structural behavior of continuous fiber composite materials often takes into account the periodicity of the underlying micro-structure. A well established method dealing with the structural behavior of periodic micro-structures is the socalled Asymptotic Expansion Homogenization (AEH). By considering a periodic perturbation of the material displacement, scale bridg...
