Model Predicts How Homogeneous Materials Fail
Antonio J. Pons, of the research group on Nonlinear Dynamics, Nonlinear Optics and Lasers of the Universitat Politècnica de Catalunya (UPC)-Barcelona Tech in Terrassa, Spain, has reportedly developed a new method for predicting and describing how materials break. This mathematical model, introduced in an article published in the March 4 issue of Nature, describes the fracture process for materials such as glass, polymers, concrete, ceramics, metals, rocks, and even certain geological fractures. The study was completed in collaboration with researcher Alain Karma, professor at Northeastern University in Boston.
Pons’ method enables the scientific community to describe the processes involved in the fracture of materials from their initial state, as the break develops, and its final outcome at all scales. In addition, the method allows for describing cracks mathematically in three dimensions. The method also enables numerical simulations that...
