Particulate Composite Damage: The Influence of Particle Shape on Crack Path
Original language description
Using stiff particles mixed into polymer matrix may significantly improve global mechanical response of the composite. Unfortunately, this process leads to other side effects, for example, presence of stress concentration at the particle-matrix interface or negative influence on the fracture toughness. The paper presents an approach to estimate the influence of particles on the micro-crack propagation. Material properties of matrix and particles were estimated experimentally. A two-dimensional computational model was proposed and all calculations were done in software ANSYS. On the base of linear elastic fracture mechanics, the influence of the particle shape on the micro-crack propagation paths was analyzed via numerical studies. The results of numerical simulations show that the shape of the particles can significantly influence the micro-crack path as well as the stress intensity factor on the crack tip, which corresponds to fracture toughness of polymer composite filled with rigid particles. The conclusions of this paper could contribute to better understanding of the behavior of the polymer composites.
