A Hybrid Approach to Composite Damage and Failure Analysis Combining Synergistic Damage Mechanics and Peridynamics
Abstract
The complexity of failure mechanisms in composite materials necessitates a multi-scale approach at different characteristic levels. This proposal brings together two approaches that each have advantages in addressing different stages of the damage evolution process. The synergistic damage mechanics (SDM) combines the classical continuum formulation of internal state variables and the micromechanics determination of local effects that provide effective measures of the variables. This approach is, however, suited to treat distributed damage entities. Once distributed cracks connect and produce complex surface geometries, the peridynamics (PD) formulation of local failure is effective in addressing damage evolution. Combining SDM and PD in a seamless way is the main objective of the proposal, with the ultimate goal of predicting damage and failure of fiber-reinforced composites in the presence of manufacturing defects.
