Journal Article
Guerra, N. B., Pires, A. V., Matthews, S., Szyniszewski, S., & Vieira Jr., L. (2023). An optimization method for stochastic reconstruction from empirical data - A limestone rock strain fields study-case using digital image correlation data. MethodsX, 10, Article 102141. https://doi.org/10.1016/j.mex.2023.102141

Stochastic field reconstruction is a crucial technique to improve the accuracy of modern rock simulation. It allows explicit modelling of field conditions, often employed in uncertainty quantification analysis and upsampling and upscaling procedures....

Topology-optimized bulk metallic glass cellular materials for energy absorption (2021)
Journal Article
Carstensen, J. V., Lotfi, R., Chen, W., Szyniszewski, S., Gaitanaros, S., Schroers, J., & Guest, J. K. (2022). Topology-optimized bulk metallic glass cellular materials for energy absorption. Scripta Materialia, 208, 114361. https://doi.org/10.1016/j.scriptamat.2021.114361

Topology optimization is increasingly being used to design the architecture of porous cellular materials with extreme elastic properties. Herein, we look to extend the design problem to the nonlinear regime and aim to maximize the energy absorption c...

Non-cuttable material created through local resonance and strain rate effects (2020)
Journal Article
Szyniszewski, S., Vogel, R., Bittner, F., Jakubczyk, E., Anderson, M., Pelacci, M., Chinedu, A., Endres, H.-J., & Hipke, T. (2020). Non-cuttable material created through local resonance and strain rate effects. Scientific Reports, 10, Article 11539. https://doi.org/10.1038/s41598-020-65976-0

We have created a new architected material, which is both highly deformable and ultra‐resistant to dynamic point loads. The bio-inspired metallic cellular structure (with an internal grid of large ceramic segments) is non-cuttable by an angle grinder...

Damping of selectively bonded 3D woven lattice materials (2018)
Journal Article
Salari-Sharif, L., Ryan, S. M., Pelacci, M., Guest, J. K., Valdevit, L., & Szyniszewski, S. (2018). Damping of selectively bonded 3D woven lattice materials. Scientific Reports, 8(1), Article 14572. https://doi.org/10.1038/s41598-018-32625-6

The objective of this paper is to unveil a novel damping mechanism exhibited by 3D woven lattice materials (3DW), with emphasis on response to high-frequency excitations. Conventional bulk damping materials, such as rubber, exhibit relatively low sti... Read More about Damping of selectively bonded 3D woven lattice materials.
