Abstract
Particles are provided which have a bulk modulus that varies nonlinearly with changes in pressure. The shell having a shell and a core is manufactured from a solid elastic material as a tube shape with a closure at both ends. The core is manufactured from a material having a bulk modulus less than the bulk modulus of the shell material and is pressurized. A system for fabricating the particles operationally includes a first pair of crimping wheels, a second pair of crimping wheels, and a pair of cutting wheels. During manufacture, feed stock is fed along a central line of symmetry; first passing between the first pair of crimping wheels, between the second pair of crimping wheels, and then between the cutting wheels. Particles are created by crimping, sealing and cutting sections of the feed stock to form individual or strings of particles.
