Towards active stiffness control in pattern-forming pneumatic metamaterials
Ondřej Faltus, Milan Jirásek, Martin Horák +4
Pattern-forming metamaterials feature microstructures specifically designed to change the material's macroscopic properties due to internal instabilities. These can be triggered ei…
High-resolution numerical-experimental comparison of heterogeneous slip activity in quasi-2D ferrite sheets
J. Wijnen, T. Vermeij, J. P. M. Hoefnagels +2
The role of heterogeneity in the plastic flow of thin ferrite specimens is investigated in this study. This is done through a recently introduced quasi-2D experimental-numerical fr…
Discrete slip plane analysis of ferrite microtensile tests: On the influence of dislocation source distribution and non-Schmid effects on slip system activity
J. Wijnen, J. P. M. Hoefnagels, M. G. D. Geers +1
The slip system activity in microtensile tests of ferrite single crystals is compared with predictions made by the discrete slip plane model proposed by Wijnen et al. (Internationa…
A Comparative Study of Enriched Computational Homogenization Schemes Applied to Two-Dimensional Pattern-Transforming Elastomeric Mechanical Metamaterials
S. O. Sperling, T. Guo, R. H. J. Peerlings +3
Elastomeric mechanical metamaterials exhibit unconventional behaviour, emerging from their microstructures often deforming in a highly nonlinear and unstable manner. Such microstru…
Integrated Digital Image Correlation for Micro-Mechanical Parameter Identification in Multiscale Experiments
O. Rokoš, R. H. J. Peerlings, J. P. M. Hoefnagels +1
Micromechanical constitutive parameters are important for many engineering materials, typically in microelectronic applications and material design. Their accurate identification p…
An effective anisotropic visco-plastic model dedicated to high contrast ductile laminated microstructures: Application to lath martensite substructure
V. Rezazadeh, R. H. J. Peerlings, F. Maresca +2
In particular types of layer- or lamellar-like microstructures such as pearlite and lath martensite, plastic slip occurs favorably in directions parallel to inter-lamellar boundari…
