Experimental study on impacted composite laminates under static and fatigue loading

The intended objectives of the reported project are that the experimental investigations are executed on the T-C fatigue damage growth mechanisms of both the impacted specimens and specimens with artificial delaminations of similar locations and sizes as measured in the impacted specimens, i.e. an experimental modelling of damage and the above mentioned tests are expected to quantify the effects of delamination and layer cracking in relation to the remaining other damages as debonding, etc. If the amount of the remaining damage is small compared with that of the delamination and layer cracking, only specimens with artificial delaminations will be numerically analysed to model the fatigue damage growth of the impacted specimens. However, the present experimental investigation of the fatigue behaviour of the line - nose impacted specimens has shown that, due to some typical damage characteristics, the idea of the proposed project is far away from the test results. In this report, only the test results on the line-nosed impact damage and behaviour under fatigue loading are discussed.
