“…An approach for the mixed-dimensional coupling of analysis models is described in [6]. Dimensional interfaces describe the connection between adjacent regions of different dimensionality and are defined by using face-splitting techniques to create the topological link between adjacent regions, e.g.…”

“…The model aims to characterise random fibre materials containing large filament count bundles (>3K) and high fibre volume fractions (~50%). Fibre bundles are modelled as shells using a so-called mixed-dimensional modelling strategy [32], which enables the bundles to be redistributed and compressed to simulate pressure being applied from a matched mould tool. A force-directed algorithm is adopted to simulate the through-thickness compliance of the fibre bundles, in order to achieve realistic local fibre distributions.…”

A geometrical modelling scheme is presented to produce representative architectures for discontinuous fibre composites, enabling downstream modelling of mechanical properties. The model generates realistic random fibre architectures containing high filament count bundles (>3k) and high (~50%) fibre volume fractions. Fibre bundles are modelled as thin shells using a multi-dimension modelling strategy, in which fibre bundles are distributed and compacted to simulate pressure being applied from a matched mould tool. FE simulations are performed to benchmark the in-plane mechanical properties obtained from the numerical model against experimental data, with a detailed study presented to evaluate the tensile properties at various fibre volume fractions and specimen thicknesses. Tensile modulus predictions are in close agreement (less than 5% error) with experimental data at volume fractions below 45%.Ultimate tensile strength predictions are within 4.2% of the experimental data at volume fractions between 40%-55%. This is a significant improvement over existing 2D modelling approaches, as the current model offers increased levels of fidelity, capturing dominant failure mechanisms and the influence of out-of-plane fibres.

“…Thakur et al [10] have presented a review on geometric simplification methods for CAE analysis from CAD models. Since the simplified geometric models for CAE are usually composed of entities with mixed dimensions, the analytical coupling between the meshes with different dimensions has also been studied by some scholars [11]. Although the geometric adaptation could be conducted in CAD systems, current industrial practice prefers to accept it as a step of the pre-process in CAE systems.…”

CAD-CAE integration is an important issue for complex structure optimization, which automatically transforms the geometric model from CAD systems to CAE systems and maintains the associations of different types of information after design variables are updated. In composite laminate design optimization (CLDO), the design variables include not only geometric dimensions but also fiber orientation angles and laminate thickness of different plies at individual middle surfaces of a compound shell structure, which makes the information association maintenance more difficult. This paper proposes a CAD-CAE integration scheme for CLDO. In this scheme, an analysis task description for parametric CAD model is created to guide the automatic FEA modeling and analysis process in CAE systems on the basis of parameterindependent identifiers for geometric entities. The permanent naming for geometric entities shared by both CAD and CAE systems is achieved with a marking-point approach and it helps maintaining the association relations between geometric objects and their physical information for different parameters. The proposed approach has been successively applied to create the automatic procedures for static and modal analyses of a complex parameterized shell structure in its CLDO. 
