Mathematical Methods in the Applied Sciences, Volume 48, Issue 1, Page 926-979, 15 January 2025.We employ the theory of asymptotic homogenization (AH) to study the elasto‐plastic behavior of a composite medium comprising two solid phases, separated by a sharp interface and characterized by mechanical properties, such as elastic coefficients and “initial yield stresses” (i.e., a threshold stress above which remodeling is triggered), that may ...

Stability of pulse-like earthquake ruptures [PDF]
, 2019 Pulse-like ruptures arise spontaneously in many elastodynamic rupture simulations and seem to be the dominant rupture mode along crustal faults. Pulse-like ruptures propagating under steady-state conditions can be efficiently analysed theoretically, but ...

Earth Surface Processes and Landforms, Volume 49, Issue 15, Page 5054-5068, December 2024.An ice‐contact delta developed at the head of Eyre Fjord in the 21st century. This resulted in a shift in sediment input from diffuse to point sources at the fjord head, leading to more frequent and stronger turbidity currents in the fjord. Abstract Pio XI Glacier (49°S) is the largest and one of the very few advancing glaciers in Patagonia.

Proceedings in Applied Mathematics and Mechanics, Volume 24, Issue 4, December 2024.ABSTRACT In the present study, the nonlinear material law of an in‐house FEM solver is substituted by physics‐informed neural networks (PINNs) and by physics‐based spiking neural networks (SNNs) for predicting the dynamic response of beams under impact loading.

The Peierls--Nabarro FE model in two-phase microstructures -- a comparison with atomistics
, 2020 This paper evaluates qualitatively as well as quantitatively the accuracy of a recently proposed Peierls--Nabarro Finite Element (PN-FE) model for dislocations by a direct comparison with an equivalent molecular statics simulation.

Microstructural and Micromechanical Evolution of Olivine Aggregates During Transient Creep
Journal of Geophysical Research: Solid Earth, Volume 129, Issue 12, December 2024.Abstract To examine the microstructural evolution that occurs during transient creep, we deformed samples of polycrystalline olivine to different strains that spanned the initial transient deformation. Two sets of samples with different initial grain sizes of 5 μm and 20 μm were deformed in torsion at T = 1,523 K, P = 300 MPa, and a constant shear ...

A thermoviscoplastic model with damage for simultaneous hot/cold forging analysis [PDF]
, 2013 A constitutive model is presented for simultaneous hot/cold forming processes of steels. The phenomenological material theory is based on an enhanced rheological model and accounts temperature dependently for nonlinear hardening, thermally activated ...

Identification of nonlinear kinematic hardening constitutive model parameters using the virtual fields method for advanced high strength steels [PDF]
In this work, the nonlinear kinematic hardening combined with Voce isotropic hardening was selected to characterize the material behavior of advanced high strength steel sheet samples subjected to a few reverse loading cycles.
