Nowadays some aspects of the nucleation and critical or subcritical crack propagation in a solid could be simulated with good accuracy. Classical numerical methods base on the continuum hypotheses such as the Finite Element Method and Boundary Element Method let to furnish responses in several cases. Also it is known that the changes that happen when a discontinuity appears in the solid forming a crack or let its propagation is very complex and demands analysis in several scales.
In this context methods that do not use the continuum premise as the called discrete numerical methods could be given complementary information concerning the classical methods cited before.
In this Symposium, we invite to present works related to crack nucleation and propagation using as a tool of analysis numerical discrete methods such us the Peridynamics, the Method based on the built of reticulated formed by bars or beams and also works base on the apparently simple models such as the Bundle and Fuse Models among others let concentrate our attention in the common characteristic in the critical phenomena linked with the crack grow without taking into account the particularities relate with the geometry and boundary conditions.
