Understanding the fracture mechanisms and predicting failure in forming processes is of
great interest to increase formability and numerical methods have been proven effective …

Flow forming is an incremental metal-forming technique used for manufacturing thin-walled
seamless tubes where a hollow metal material flows axially along the mandrel by a rotating …

Flow forming is a metal forming process for cylindrical workpieces where high velocity
deformation leads to radial thinning and axial extension. In the current study, a …

This research was devoted to unveiling the strain rate sensitivity (SRS) of G18NiCrMo3-6
cast steel in tension/compression asymmetry. For that purpose, detailed mechanical …

The aim of this study is to calibrate the parameters of the Johnson-Cook (JC) and modified
Mohr-Coulomb (MMC) ductile failure models for Inconel 718 and predict the formability limit …

In this paper, derivation and implementation of a micromechanically motivated traction
separation law for cohesive zone modeling of ductile fracture is discussed. The formulation …

Gaining popularity after its coupling with the finite element method, cohesive zone modelling
has been used extensively to model fracture, especially in delamination problems. Its …

Flow forming, also known as tube spinning, is an advanced metal forming process that
produces thin-walled, high-precision cylindrical components. This process involves …

This thesis presents a numerical study of the behavior of metal targets subjected to ballistic
impact and shaped charge impact, utilizing finite element (FE) and smoothed particle …

Ductile damage and fracture are known to be driven by the microvoid nucleation, growth,
and coalescence. Porous micromechanical description of the ductile metals led to many …
