Fatigue damage evolution in GFRP laminates with constrained off-axis plies

摘要: The characterisation of fatigue damage evolution in constrained glass fibre reinforced plastic off-axis laminates is presented. A newly developed imaging technique known as Automatic Crack Counting (ACC) used to quantify the crack state constant amplitude (CA) and variable (VA) block loading tension-tension tests compression-tension tests. quantified states are analysed by combining ACC method with a data mining approach applying these large sets obtained during It shown that for stress level, stochastic nature initiation growth accurately modelled Weibull distribution, distribution parameters being efficiently derived using approach. data-rich provides new insight density process VA C-T loading, well combination classical S-N curves Paris’ Law relationship. Hence, providing an improved includes deterministic information physically based modelling loading.
