Numerical modeling of hypervelocity impacts

Two-dimensional thermal simulations of aluminum and carbon ion strippers for experiments at SPIRAL2 using the highest beam intensities

“…The beam-target heating simulations presented in this section have been carried out using a three-dimensional computer code, PIC3D [38], that is based on a finite-size particle-in cell algorithm and includes ion energy deposition as well as heat conduction. The code has recently been extended to include thermal radiation losses from the target surface and the details of the mathematical model are given in [33].…”

High Energy Density Physics Studies at the Facility for Antiprotons and Ion Research: the HEDgeHOB Collaboration

“…As the Bragg peak lies outside the target, energy deposition is fairly uniform along the particle trajectory and the problem becomes two-dimensional. We therefore use twodimensional version of a 3D code, PIC3D [72] and perform the simulations along the cylinder cross section in the middle of the target (half length of the cylinder). We assume a beam intensity of 10 10 uranium ions per spill.…”

Axial cutting of AA6061-T6 circular extrusions under impact using single- and dual-cutter configurations

“…The use of an Eulerian element in numerical simulations has historically been associated with fluid mechanics problems [19] and recently has seen more implementation in solid mechanics problems associated with high-velocity impacts [20][21][22][23] and, more relevant to this study, metal cutting [24][25][26]. Benson [27] provides an overview of the applicability of the Eulerian element formulation for solid mechanics problems and indicates that structural problems involving changing topology may be better suited for this type of element.…”
