Abstract
Material assemblies combining composites, metals, and ceramics are increasingly used in
structural applications due to their high strength-to-weight ratios and durability. However,
disassembling such multilayered systems without damaging the constituent materials
remains a challenge, particularly for recycling or repair purposes. Magnetic pulse
technology offers a promising solution by generating transient mechanical loads through
Lorentz forces induced in conductive layers. This paper aims to define the operating
conditions of a high-power pulsed (HPP) generator capable of inducing controlled
delamination in laminate structures. A simplified model of the current delivered by an HPP
generator is introduced, and its temporal evolution is related to the mechanical load applied
to the laminate. Previously established delamination criteria, derived from a one dimensional
wave propagation analysis using the method of characteristics, are
reinterpreted to guide the design of an HPP generator. The required frequency and magnetic
field amplitude are then expressed as functions of the laminate's acoustic and geometric
properties. The results provide a set of design criteria for HPP generators in magnetic pulse
disassembly applications, enabling effective and selective separation of bonded layers in
multi-material systems.
