behavior of woven Glass Fiber Reinforced Polymer (GFRP) composites under Mode I
crack growth was experimentally investigated and numerically modelled, to
determine the effects of lay-up sequence and widths on delamination resistance.
Different methods are used for calculation of strain energy release rate
(SERR): for experimental solution, experimental compliance calibration method
(CCM), modified beam theory (MBT), modified compliance calibration (MCC) are
used and virtual crack closure technique (VCCT) are used for numerical solution.
To achieve this aim DCB (double cantilever beam) test specimens are used to
evaluate the SERR values. Three dimensional finite element model is used to
perform the delamination, crack analysis, and Mode I SERR value is calculated
by the VCCT. It is seen that there is an agreement between experimental and
numerical results so that VCCT method is to be an appropriate method for
analyzing a SERR value of woven glass fiber reinforced polimer composites. </span> <br /> </p>}, number={62}, publisher={Dokuz Eylül Üniversitesi}
