Different approaches for data evaluation and their effect on the in- and inter-laboratory scatter are discussed and compared. Calculated delamination rates da/dN and applied GImax from displacement controlled tests are sensitive to small scatter in the load signal, and, therefore, a new route to evaluate the crack growth rate from pairs of load and displacement data is presented.||Type of material:||Journal Article||Publisher:||Elsevier||Copyright (published version):||2014 Elsevier||Keywords:||Polymer–matrix composites (PMCs); Delamination; Fatigue; Fracture; Test development||DOI:||10.1016/j.engfracmech.2013.12.002||Language:||en||Status of Item:||Peer reviewed|
