Rate-dependency analysis of mode I delamination by means of different data reduction strategies for the GDCB test method
The loading-rate mechanical response of the mode I delamination in composites and adhesively bonded joints was investigated. The tests were carried out using a recently developed Guided Double Cantilever Beam test method. Three different data reduction methods were proposed and assessed: a displacem...

| Sumario: | The loading-rate mechanical response of the mode I delamination in composites and adhesively bonded joints was investigated. The tests were carried out using a recently developed Guided Double Cantilever Beam test method. Three different data reduction methods were proposed and assessed: a displacement-based formulation, a near-crack-tip displacement formulation, and a numerical assessment using the Virtual Crack-Closure Technique method. The methods account for the dynamic effects which may be present. While small differences between the three different methods can be seen, no rate-dependency higher than the uncertainty for the materials and the loading rates considered have been evidenced |
