Fracture‐mechanical numerical simulation of punching in reinforced concrete foundations considering soil‐structure interaction and design code evaluation

Structural Concrete, EarlyView.
Abstract Current design provisions for punching shear in foundations, including Eurocode 2 (2023) and fib Model Code 2020, are mechanically based models partly calibrated against experimental data from isolated flat slabs and foundation specimens. The available experimental database for foundations is small and only partly representative of realistic ...

Triaxial compression experiments on plain concrete

, 2009
This M.E. project report describes the main aspects and findings of an experimental research project on triaxial compression of plain concrete. The main focus of the research is to study the behavior of plain concrete under increasing axial compression ...

Comparison of Mesoscale Crack Advance and Process Zone Element Approaches for Simulating Ductile Crack Trajectories in Steel

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Rigorous application of continuum damage mechanics (CDM) models coupled with crack propagation schemes can predict crack branching or zigzag trajectories near the crack tip, even when the macroscopic crack growth is straight. This arises from oscillations in the local damage field and is consistent with experimental observations of ductile ...

A generalized nonlinear three-dimensional Hoek‒Brown failure criterion

Journal of Rock Mechanics and Geotechnical Engineering
To understand the strengths of rocks under complex stress states, a generalized nonlinear three-dimensional (3D) Hoek‒Brown failure (NGHB) criterion was proposed in this study.

Transcranial electric stimulation in chronic pain: Effects on quality of life, physical function, activity and clinical status

Journal of Neuropsychology, EarlyView.
Abstract Transcranial electric stimulation represents a promising non‐invasive neuromodulatory technique targeting maladaptive nociplastic changes in chronic pain (CP) with analgesic effects. However, its impact beyond pain reduction on broader outcomes such as quality of life (QoL) and physical function remains unclear.
