Finite element analysis of failure modes in dynamically loaded pre-cracked steel plates
… of the notch ligament. The computations employed Johnson - Cook model which takes into account strain hardening, strain-rate hardening and thermal softening. An approximate solution of the governing equations is sought by using an explicit finite element code DYNA2D. We analyzed the evolution of …

Large strain computational modeling of high strain rate phenomena in perforating gun devices by Lagrangian/Eulerian FEM simulations
… Particular reference is made to the modeling of metallic materials, although other kinds of materials are considered as well. The work may be divided into three main parts. The first part of the work consists in a critical review of the constitutive modeling of materials subjected to …

Machining of additively manufactured titanium Ti-6Al-4V; cutting forces and chip morphology
… (AM) titanium Ti-6Al-4V and presents a model to determine Johnson Cook (J-C) constitutive parameters from complex machining processes through numerical modeling and experimental validation. The J-C parameters are important in describing the characteristics and behaviors of materials …
