Abstract: The experimentally detected phenomenon of compression fracture of a composite ring made of unidirectional fiberglass plastic under initial internal impulsive (explosive) loading is analyzed. Fracture results from bending in the compression phase because of loss of stability of the radial axisymmetric mode of motion.
