Axial-Compressive Behavior, Including Kink-Band Formation and Propagation, of Single p-Phenylene Terephthalamide (PPTA) Fibers
Figure 9
Coarse-grained microstructure, during axial compression, within the computational cell containing (initially) defective virgin PPTA fiber at the longitudinal stretch values of: (a) 0.975; (b) 0.950; (c) 0.925; and (d) 0.900. The fiber within the computational cell contains a cluster of side-group defects.
