Comparison of numerical methods for cerebrospinal fluid representation and fluid-structure interaction during transverse impact of a finite element spinal cord model

Aleksander Rycman et al.

Summary: Spinal cord impacts can have devastating consequences and computational models investigating such impacts need biofidelic numerical representations. This study assessed the biofidelity and efficiency of fluid-structure interaction methods with cerebrospinal fluid during transverse impact, finding that smoothed particle hydrodynamics and arbitrary Lagrangian-Eulerian methods were effective, with the former being more computationally efficient.

Realistic head-shaped phantom with brain-mimicking metabolites for 7 T spectroscopy and spectroscopic imaging

Ghil Jona et al.

Summary: This study aimed to develop and characterize a realistic head-shaped phantom filled with brain-mimicking metabolites for MRS and magnetic resonance spectroscopic imaging at 7 T. The phantom was designed to provide similar B(0) and B(1) distributions and T(1)/T(2) relaxation values to those of human brain, and was evaluated for localized spectroscopy, fast spectroscopic imaging, and fat suppression.

Smoothed particle hydrodynamic modelling of the cerebrospinal fluid for brain biomechanics: Accuracy and stability

Harry Duckworth et al.

Summary: This study explored the stability and accuracy of key modelling parameters of an SPH model of the CSF when predicting relative brain/skull displacements. The Moving Least Squares (MLS) SPH formulation and Ogden rubber material model were found to be the most accurate and stable. Differences in strain and strain rate were observed between the SPH and FE models of CSF, with FE mesh anchoring the gyri and SPH showing higher levels of strains in the sulci. Tensile instability was identified as a key challenge of the SPH method, highlighting the need for further research in addressing this issue.

Experimental and Numerical Study of Ballistic Resistance of Composites Based on Sandwich Metallic Foams

Anna Dmitruk et al.

Summary: The study focuses on testing the energy absorption capacity of Zn-Al alloys filled with various polymer materials, such as epoxy resin, polyurethane resin and silicone, as ballistic barriers and kinetic energy absorbers. The ballistic resistance of modern hybrid materials is examined through direct firing and quasi-static piercing tests, along with numerical simulations in the ABAQUS environment. Results show that metallic foams have minimal influence on impact loads, while polyurethane resin filled foams exhibit resistance to overshoot, supporting detailed analysis of impact energy dissipation for each sample.

Impact analysis of a honeycomb-filled motorcycle helmet based on coupled head-helmet modelling

Shunfeng Li et al.

Summary: The study developed a methodology for analyzing a novel motorcycle helmet by coupling head-helmet modeling and kinematic and biomechanical head injury criteria. The research aimed to improve the protective performance of helmets and reduce head injuries through an optimization study on honeycomb filler geometries and liner foam densities. The proposed method can be applied in structural crashworthiness studies where human-structure interaction is crucial.
