Anisotropic ductile fracture: experiments, modeling, and numerical simulations
Journal of Materials Research and Technology, 2022 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
Metals, 2021 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

Applied Sciences, 2017 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
Proceedings in Applied Mathematics and Mechanics, Volume 19, Issue 1, November 2019., 2019 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 ...

A Finite Volume Framework for Damage and Fracture Prediction in Wire Drawing
International Journal for Numerical Methods in Engineering, Volume 126, Issue 1, 15 January 2025.ABSTRACT This article presents the implementation of the canonical Lemaitre and Gurson–Tvergaard–Needleman (GTN) damage models and a more recent phase‐field type model within a Lagrangian, geometrically nonlinear, cell‐centred finite volume framework. The proposed segregated solution procedure uses Picard‐type defect (deferred) outer corrections, where
