Numerical modeling of the fracture of composite laminates in impact
Abstract
The damage and fracture behavior of composite materials under conditions of low-velocity impact is investigated in the context of the theory of layered media with a periodic structure. Results of a numerical experiment are presented for a wide range of loads, impact times, and layer stiffness ratios. The number of cracks and their distribution over the thickness of a composite are investigated as a function of the composite characteristics, interface conditions, and impact parameters.
