Dynamically Driven Phase Transformations in Damaged Composite Materials
- Theoretical Division, MS B221, LANL, Los Alamos, NM 87545 (United States)
A model developed for composite materials undergoing dynamicaly driven phase transitions in its constituents has been extended to allow for complex material micro-structure and evolution of damage. In this work, damage is described by interfacial debonding and micro-crack growth. We have applied the analysis to silicon carbide-titanium (SiC-Ti) unidirectional metal matrix composites. In these composites, Ti can undergo a low pressure and temperature solid-solid phase transition. With these extensions we have carried out simulations to study the complex interplay between loading rates, micro-structure, damage, and the thermo-mechanical response of the system as it undergoes a solid-solid phase transitions.
