Finite element simulation of ring expansion and fragmentation: The capturing of length and time scales through cohesive models of fracture
TL;DR: In this article, the expanding ring test of Grady and Benson (1983) is taken as a convenient yet challenging validation problem for assessing the fidelity of cohesive models in situations involving ductile dynamical fracture.

Fragmentation of metal rings by electromagnetic loading
D. E. Grady,D. A. Benson +1 more
TL;DR: In this paper, a method for performing fragmentation studies on rapidly expanding metal rings is described, where a fast-discharge capacitor system generates magnetic forces which accelerate the rings to maximum radial velocities of approximately 200 m/s corresponding to circumferential-strain rates of approximately 104/s at fragmentation.

The Effect of Tool–Sheet Interaction on Damage Evolution in Electromagnetic Forming of Aluminum Alloy Sheet
TL;DR: In this article, the effect of tool-sheet interaction on damage evolution in electromagnetic forming is studied, and a parametric numerical analysis is carried out to quantify damage in the parts and to confirm the numerical results.
Journal ArticleDOI
Inertia and thermal effects on the localization of plastic flow
TL;DR: In this article, the influence of inertia and thermal effects on the ductility is studied within the theoretical framework of a one-dimensional model for uniaxial tension, and a linearized study of stability is discussed; nonlinear quasi-static and dynamic analyses are presented; they allow for a proper description of at least a part of the dynamic growth, and the adiabatic decrease of ductility.

Effect of velocity on flow localization in tension
Xiaoyu Hu,Glenn S. Daehn +1 more
TL;DR: In this paper, one-dimensional dynamic numerical simulations of sheet tensile tests and expanding ring tests have been carried out to study the variation of ductility over a wide range of deformation velocities where inertial effects are significant.
