Prediction method for ductile crack initiation and growth resistance for pre-strained steel based on ductile damage model

open access: yesNihon Kikai Gakkai ronbunshu, 2023
This study aims to develop a numerical simulation-based method for predicting ductile crack growth resistance curve (R-curve) for pre-strained components for rational assessment of ductile crack growth controlling fracture for pre-strained structural ...

Low cycle fatigue of components manufactured by rod extrusion: Experiments and modeling

open access: yesAdvances in Industrial and Manufacturing Engineering, 2023
The performance of formed components is significantly influenced by the initiation of ductile damage. Preceding forming operations, for instance, affect the service life determined in fatigue tests.

Microstructural topology effects on the onset of ductile failure in multi-phase materials - a systematic computational approach [PDF]

open access: yes, 2015
Multi-phase materials are key for modern engineering applications. They are generally characterized by a high strength and ductility. Many of these materials fail by ductile fracture of the, generally softer, matrix phase.

Correlating Ultrasonic Velocity in DC04 with Microstructure for Quantification of Ductile Damage

open access: yesJournal of Manufacturing and Materials Processing, 2023
The detection of ductile damage by image-based methods is time-consuming and typically probes only small areas. It is therefore of great interest for various cold forming processes, such as sheet-bulk metal forming, to develop new methods that can be ...

Exploring the effect of stress-strain behavior of cemented tailings backfill on the stability of inclined sill mat: A numerical study

open access: yesAlexandria Engineering Journal, 2023
This study aims to investigate the impact of the stress–strain behaviour of cemented tailings backfill (CTB) on the stability of sill mat structures used in underhand cut-and-fill mining.

Regularizational approach for modeling ductile damage [PDF]

open access: yesMATEC Web of Conferences, 2019
It is well known, that modeling of material softening behavior can lead to ill-posed boundary value problems. This, in turn, leads to meshdependent results as far as the finite-element-method is concerned [1].

On the regularization for ductile damage models [PDF]

open access: yesPAMM, 2019
AbstractModeling softening behavior often leads to ill‐posed boundary value problems. This, in turn, results in pathological mesh‐dependent computations as far as the finite‐element‐method is concerned. A by now widely used technique to eliminate these problems is the micromorphic approach by [1,2].
