Mirkhalaf, Mohsen (author), Rocha, I.B.C.M. (author)During the last few decades, industries such as aerospace and wind energy (among others) have been remarkably influenced by the introduction of high-performance composites. One challenge, however, for modeling and designing composites is the lack of computational efficiency of accurate high-fidelity models. For design purposes, using...journal article 2024

Hofman, P. (author), Ke, L. (author), van der Meer, F.P. (author)A common choice for multiscale modeling of the mechanical response of composites is to use periodic boundary conditions (PBCs) on square and cubical representative volume elements (RVEs). However, when strain localization occurs in the micromodel, these PBCs are unable to reproduce the transverse isotropy of composite materials with a random...journal article 2022

Joustra, J.J. (author), Bakker, C.A. (author), Bessai, R. (author), Balkenende, R. (author)The design of composite products for a circular economy is challenging. Materials such as glass-fibre-reinforced plastics have long product lifetimes but are hard to recycle. For the effective reuse and recycling of products, parts, and materials, recovery strategies must be selected and implemented in the product design stage. This extends the...journal article 2022

Joustra, J.J. (author), Flipsen, Bas (author), Balkenende, R. (author)Composite materials are an attractive material choice as they enable lightweight, low-maintenance products with a long lifespan. Recycling these materials, however, remains a chal-lenge. Homogeneous material composition and the use of thermoset matrices complicate repro-cessing, and result in low-grade recyclate. This means that closing the...journal article 2021

Pascoe, J.A. (author)Using the slow-growth certification approach for damage tolerance of composite aircraft structures has the potential to reduce their weight. Applying this approach requires that damage growth is slow, stable, and predictable. However, currently available methods do not allow for sufficiently accurate predictions, due to knowledge gaps related...journal article 2021

Joustra, J.J. (author), Flipsen, Bas (author), Balkenende, R. (author)Composite materials offer many advantages during the use phase, but recovery at the end of a lifecycle remains a challenge. Structural reuse, where an end of life product is segmented into construction elements, may be a promising alternative. However, composites are often used in large, complex shaped products with optimised material...journal article 2021
