A note on thermomechanical coupling effects in the indentation of pseudoelastic shape memory alloys
Mohsen Rezaee-Hajidehi, Mahdi Neghabi, Stanislaw Stupkiewicz
While macroscopic experiments on polycrystalline shape memory alloys (SMAs) reveal significant thermomechanical coupling effects arising from the latent heat of transformation, the…
Twin branching in shape memory alloys: a 1D model with energy dissipation effects
Stanislaw Stupkiewicz, Seyedshoja Amini, Mohsen Rezaee-Hajidehi
We develop a 1D model of twin branching in shape memory alloys. The free energy of the branched microstructure comprises the interfacial and elastic strain energy contributions, bo…
Energy and morphology of martensite-twinned martensite interface in CuAlNi shape memory alloy: a phase-field study
Seyedshoja Amini, Mohsen Rezaee-Hajidehi, Stanislaw Stupkiewicz
Needle-like twins are observed experimentally within the transition layer at the martensite-twinned martensite interface. We utilize a phase-field approach to investigate this micr…
Exploiting high-contrast Stokes preconditioners to efficiently solve incompressible fluid-structure interaction problems
Michał Wichrowski, Piotr Krzyżanowski, Luca Heltai +1
In this work, we develop a new algorithm to solve large-scale incompressible time-dependent fluid--structure interaction (FSI) problems using a matrix-free finite element method in…
Indentation-induced martensitic transformation in SMAs: insights from phase-field simulations
Mohsen Rezaee-Hajidehi, Karel Tůma, Stanisław Stupkiewicz
Direct experimental characterization of indentation-induced martensitic microstructures in pseudoelastic shape memory alloys (SMAs) is not possible, and thus there is a lack of evi…
Phase-field modeling of multivariant martensitic transformation at finite-strain: computational aspects and large-scale finite-element simulations
K. Tůma, M. Rezaee-Hajidehi, J. Hron +2
Large-scale 3D martensitic microstructure evolution problems are studied using a finite-element discretization of a finite-strain phase-field model. The model admits an arbitrary c…
Finite deformations govern the anisotropic shear-induced area reduction of soft elastic contacts
J. Lengiewicz, M. de Souza, M. Lahmar +4
Solid contacts involving soft materials are important in mechanical engineering or biomechanics. Experimentally, such contacts have been shown to shrink significantly under shear,…
Bifurcation of elastic solids with sliding interfaces
D. Bigoni, N. Bordignon, A. Piccolroaz +1
Lubricated sliding contact between soft solids is an interesting topic in biomechanics and for the design of small-scale engineering devices. As a model of this mechanical set-up,…
Implicit yield function formulation for granular and rock-like materials
S. Stupkiewicz, R. Denzer, A. Piccolroaz +1
The constitutive modelling of granular, porous and quasi-brittle materials is based on yield (or damage) functions, which may exhibit features (for instance, lack of convexity, or…
