Materials and structures in mechanics

From the PEEK microstructure at welded interfaces to the mechanical properties of thermoplastic composites manufactured by a Laser-Assisted Tape Placement process

The Laser-Assisted Tape Placement (LATP) process of thermoplastic composites enables the rapid production of laminates. However, it generates cooling rates gradients between the surface and the bulk of the plies, probably causing a crystallinity…

Multi-scale characterization of carbon-fibre reinforced PEEK composites manufactured by laser-assisted tape placement

The Laser-Assisted Tape Placement forming process of thermoplastic composites enables the rapid production of laminates. However, it requires the tuning of the processing parameters, which is currently limited by a misunderstanding of the…

Investigation Into Debonding of Single Polypropylene Fiber Pullout in Concrete Using X-Ray Microtomography and Mechanically Regularized Digital Volume Correlation

To investigate the debonding process, an in-situ pullout experiment on an indented single polypropylene fiber was conducted using X-ray microtomography. This study utilized mechanically regularized global digital volume correlation (Reg-G-DVC) to…

Polar textures in multiferroic BiFeO 3 -based superlattices

Recently, ferroelectric-based superlattices (SLs) have emerged and leaded to the discovery of exotic polar textures such as skyrmionic states or vortices in PbTiO 3 /SrTiO 3 SLs [1,2]. Thus, SLs offer a unique and promising new platform to study…

Mechanism-based modelling of the viscoelastic response of a unidirectional composite ply: validation of a new transversely isotropic model through analytical and numerical homogenisation

The viscoelastic response of long fibres, polymer matrix composites is mainly due to the deviatoric response of the matrix. This single microscale mechanism, however, results in different amount of viscous relaxation for the elastic constants…
