Damage 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...
متن کاملExtensions of fiber bundle models
The fiber bundle model is one of the most important theoretical approaches to investigate the fracture and breakdown of disordered media extensively used both by the engineering and physics community. We present the basic construction of the model and provide a brief overview of recent results focusing mainly on the physics literature. We discuss the limitations of the model to describe the fai...
متن کاملBursts in a fiber bundle model with continuous damage.
We study the constitutive behavior, the damage process, and the properties of bursts in the continuous damage fiber bundle model introduced recently. Depending on its two parameters, the model provides various types of constitutive behaviors including macroscopic plasticity. Analytical results are obtained to characterize the damage process along the plastic plateau under strain controlled load...
متن کاملFiber Bundle Models for Composite Materials
In this paper we will outline the advantages of using fiber bundles in modeling disordered materials. We will present the main aspects of classical fiber bundle models (FBMs) and highlight their ability to capture some essential aspects of composite materials. We then present some extensions of the classical FBM, modifying the way of interaction of fibers, failure law, deformation state and con...
متن کاملAvalanche 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...
