Characterization of elastic-plastic and viscoplastic behavior of AS4/PEEK thermoplastic composite

Thesis/Dissertation ·
OSTI ID:5874778

The elastic-plastic and strength properties of AS4/PEEK (APC-2) thermoplastic composite were characterized with respect to temperature variation by using a one parameter plasticity model and the elastic-viscoplastic properties were characterized by using a one parameter overstress viscoplasticity model and a modified Bodner and Patom's viscoplasticity model. These plasticity and viscoplasticity models were verified further for the case of unidirectional composite panels with cutouts and in laminates with and without hole.
