steel research international, EarlyView.A cross‐scale modeling strategy is developed to predict failure and formability of DP780 steel by linking microstructural features with macroscopic behavior. Crystal plasticity and macroscopic damage models are integrated and validated through nanoindentation, in situ bending, and finite element simulations.

Metamodeling of Void Closure during Hot Flat Rolling
steel research international, EarlyView.This work aims to present a fast metamodel for void closure during hot flat rolling. The model takes into account every individual void of void distributions as found in industrial material and is capable of calculating the resulting void closure within only few seconds of computational time without loosing significant accuracy compared to expensive ...

A finite-strain hyperviscoplastic model and undrained triaxial tests of peat
, 2017 This paper presents a finite-strain hyperviscoplastic constitutive model within a thermodynamically consistent framework for peat which was categorised as a material with both rate-dependent and thermodynamic equilibrium hysteresis based on the data ...

Structural Concrete, EarlyView.Abstract Gerber half‐joints, broadly used in the last century as elements of concrete bridges, are prone to corrosion‐induced deterioration, which may lead to brittle shear collapse. It is of paramount importance to develop advanced numerical models for simulating the collapse behavior of Gerber half‐joints, taking material deterioration into account ...

Effects of grain size distribution on the initial strain shear modulus of calcareous sand [PDF]
, 2015 The soil’s small strain shear modulus, Gmax or G0, is applied in dynamic behavior analyses and is correlated to other soil properties (density and void ratio) for predicting soil dynamic behavior under seismic loadings such as earthquakes, machinery or ...

Strip loading in reinforced concrete: Mechanical modeling and experimental validation
Structural Concrete, EarlyView.Abstract Strip loading of reinforced concrete is a common problem in engineering practice. The concrete compressive strength at the load introduction can be several times higher than the uniaxial concrete compressive strength, which can be attributed to geometrical and passive confining stresses caused by load dispersion and reinforcement, respectively.

Modeling locally corroded reinforced concrete structures in non‐linear finite element analyses
Structural Concrete, EarlyView.Abstract The ingress of chlorides, originating from the use of de‐icing salts or proximity to the sea, may cause severe local reinforcement corrosion in concrete structures such as bridges, tunnels, galleries, and retaining walls. Methods are urgently required to realistically assess the load‐bearing capacity of such deteriorated structures, accounting

Compression–tension cell with sample manipulator for in situ X‐ray nanotomography experiments
Journal of Synchrotron Radiation, EarlyView.An environmental cell with fluid flow‐through capability for performing in situ nano‐mechanical experiments at X‐ray nanotomography beamlines and a sample manipulator for mounting nanotomography samples are described.In situ X‐ray nanotomography experiments where tensile or compressive force is applied on the sample require specialized equipment.

Evolution law of the soil shear band in a triaxial test based on photogrammetry technology
工程科学学报A triaxial test is a common method for studying the shear strength of soil. This test simulates actual engineering conditions; therefore, the evolution law of the shear band is universal.
