Avalanche dynamics of fiber bundle models.
We present a detailed analytical and numerical study of the avalanche distributions of the continuous damage fiber bundle model (CDFBM). Linearly elastic fibers undergo a series of partial failure events which give rise to a gradual degradation of their stiffness. We show that the model reproduces a wide range of mechanical behaviors. We find that macroscopic hardening and plastic responses are...
متن کاملAvalanche dynamics of the continuous damage fiber bundle model
We present a detailed analytical and numerical study of the avalanche statistics of the continuous damage fiber bundle model. In the model, linearly elastic fibers undergo a series of partial failure events which give rise to a gradual degradation of their stiffness. Varying the two parameters of the model, i.e. the maximum number of local failures and the degree of stiffness reduction in singl...
متن کاملSelf-organized dynamics in local load-sharing fiber bundle models.
We study the dynamics of a local load-sharing fiber bundle model in two dimensions under an external load (which increases with time at a fixed slow rate) applied at a single point. Due to the local load-sharing nature, the redistributed load remains localized along the boundary of the broken patch. The system then goes to a self-organized state with a stationary average value of load per fiber...
متن کاملDamage in fiber bundle models
We introduce a continuous damage fiber bundle model and compare its behavior with that of dry fiber bundles. Several interesting constitutive behaviors, such as plasticity, are found in this model depending on the value of the damage parameter and on the form of the disorder distribution. We compare the constitutive behavior of global load transfer models, obtained analytically, with local load...
