Journal of Prosthodontics, EarlyView.Abstract Purpose This study aimed to compare the effects of surface treatment protocols on the surface roughness and shear bond strength (SBS) of a three‐dimensional (3D)‐printable resin for definitive crowns. Materials and Methods A 3D‐printable resin for definitive crowns (Saremco Print Crowntec) was used to produce 168 specimens (10 × 10 × 2 mm3 ...

micromechanical approach for the micropolar modeling of heterogeneous periodic media
Fracture and Structural Integrity, 2014 Computational homogenization is adopted to assess the homogenized two-dimensional response of periodic composite materials where the typical microstructural dimension is not negligible with respect to the structural sizes. A micropolar homogenization is,

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT Deep material networks (DMNs) and reduced order models (ROMs) represent two distinct paradigms for scale bridging in multiscale simulations. ROMs are data‐driven approaches that construct surrogate models for the governing partial differential equations of the microscale cell problem.

On Micromechanical Modeling of Deformation of Compact Rock in Compression
Engineering Transactions, 1993 The paper proposes a simple two-dimensional damage model for low-porosity rocks loaded in compression. The sliding crack mechanism is selected as an underlying micromechanism of the inelastic deformation at the macroscale.

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT We develop a physics‐informed Fourier Neural Operator (PINO) for the surrogate modeling of full‐field responses in polycrystalline microstructures. Reference stress and strain fields are generated using an FFT‐based full‐field solver under prescribed macroscopic loading. The model maps the crystallographic orientation field q(x)$\bm{q}(\bm{x})$

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT A systematic framework for the selection and assessment of hyperelastic constitutive models for rubber‐like materials is presented. The approach integrates verification, stability, and validation within a unified methodology to ensure reliable material parameter identification.

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5701-5711, November 2026.ABSTRACT The EAC‐1A lunar mare simulant, a silty sand, was selected by the European Astronaut Center (EAC) for use in the LUNA analogue facility's lunar simulation testbed. Its stress‐ and strain‐dependent shear modulus and damping ratio were determined via resonant column testing on specimens prepared either from ambient moisture material or oven ...
