Numerical Evaluation of Surface Roughness Influences on Cold Formability of Dual‐Phase Steel
Experiments show that surface roughness condition plays a significant role in cold‐formability of dual‐phase (DP) steel sheet. A multiscale strategy is proposed to include surface roughness information into a damage mechanics model. The force–displacement from three‐point bending tests of the rough surface sheet and smooth surface sheet agree well on ...

Metal failure is often initiated by strain localization in narrow bands. In metal matrix composites, the occurrence and the consequences of this phenomenon are influenced by the material microstructure.

Anisotropic ductile fracture: experiments, modeling, and numerical simulations
The continuous hot rolling process induces anisotropy in the plastic yield and flow and results in an anisotropic ductile fracture. In this study, experiments, including uniaxial in-plane tension tests and shear tests of butterfly specimens along ...

Numerical Simulation of Some Steel Structural Elements with Uncertain Initial Porosity
The main research purpose of this work was to study the elasto-plastic responses of some fundamental steel structural elements exhibiting stochastic volumetric microvoids. The constitutive model of the steel material was consistent with the deterministic

Damage models, particularly the Gurson–Tvergaard–Needleman (GTN) model, are widely used in numerical simulation of material deformations. Each damage model has some constants which must be identified for each material.

Virtual testing of additively manufactured grid structures
Abstract Additive manufacturing lifts the restrictions of classical manufacturing methods and enables us to produce lattice structures within otherwise massive bulk material to increase the lightweight potential of technical components. In this contribution we present a multiscale approach to characterise additively manufactured lattice structures ...
