Post-Fracture Stiffness and Residual Capacity Assessment of Film-Retrofitted Monolithic Glass Elements by Frequency Change

Figure 3

Example of presently investigated film-retrofitted glass specimens: (a) initial configuration (axonometry) and (b) deliberately cracked scenario (before/at the beginning of dynamic tests); (c) fall-out of millimetric glass fragments (during tests); (d, e) final configuration (after tests) and evidence of major damage severity, due to several test repetitions and progressive debond of glass fragments.
