A multiscale modeling methodology for damage progression in polymer-based composites Conference Paper uri icon

abstract

  • Polymer-based composites are used in novel designs of jet engine fan blade containment cases. The performance of these structures is directly affected by its behavior under impact during a blade-out event. Here, we develop the basic ingredients of a multiscale modeling methodology, which includes a polymer model capable of accounting for intrinsic softening, tension-compression asymmetry, rate-sensitivity, thermal softening and kinematic-like hardening, as well as models of matrix cracking and fiber debonding. Material and fracture parameters are identified using epoxy data for various temperatures and strain rates. Results of unit-cell calculations are presented to discuss damage initiation and progression modes.
