Property-based functional gradients for biomimetic composites

Functional gradients in hard-soft interfaces are abundant in nature, and we often mimic them to create strong and tough composites. A powerful tool for the designs and fabrication of biomimetic composites is voxel-based multi-material 3D printing. Earlier researches mainly focused on using this technique in the creation of gradients based on...

An Integrated Machine Learning and Finite Element Analysis Framework, Applied to Composite Substructures including Damage

Engineering fields such as aerospace rely heavily on the Finite Element Method (FEM) as a modelling tool. In combination with the scale and complexity of the structures typically involved here, computational cost remains a traditional issue. To perform FEM analyses of such structures efficiently nonetheless, engineers rely on techniques such as...

Modelling FRP open-hole tensile tests in Abaqus

The use of fibre reinforced polymers (FRP) are stimulated in the construction industry for their remarkable corrosion resistance, good thermo-mechanical properties, high strength-to-weight ratio and high stiffness-to-weight ratio. The open-hole strength of FRP is an important parameter in a composite design because it can be representative in...

Modelling Delamination in an Equivalent Single Layer Model in Explicit Finite Element Analysis

Delamination is one of the failure modes of composites prone to happen in the case of a car crash. In the early stages of car design, finite element analysis is used as a tool to analyze structural concepts. In order to model delamination in a newly developed material model, it is analyzed in two parts: detection and effects of delamination. To...
