On the numerical simulation of laser beam cutting of hollow sphere structures

Laser beam cutting is a highly efficient technique to cut materials. The relatively small amount of energy being involved during the process results in a small heat affected zone. This characteristic makes laser beam cutting interesting for composite materials. Within this paper the cutting process...
