26 FEM Analysis (Randomized Orthotropic) The models were discretized in: RRVE for the large angle beam RRVE for the medium angle beam RRVE for the small angle beam Each RRVE has elastic orthotropic material properties assigned independently from the neighboring ones and generated by running the stochastic laminate analogy code in Matlab. The discretization of the specimen into RRVE s has no relation with the mesh size. The nodes of neighboring RRVE s are merged to ensure displacement compatibility. For each geometry (large, medium, small): 30 FEM runs 1 fixed angle beam orientation (0 degree shown) 8 strain gage locations After FEM run, data is reduced: obtain value of normal strain at SG location Of the 30 values generated, only the MAX, AVG, MIN are reported Longitudinal Strain (x-direction) 26

42 Conclusions Prediction based on orthotropic (quasi isotropic) layered with E 1 =E 2 =E AVGEXPER are not sufficient All data points fit in the admissible region for the large & medium beams. Small beams fall outside region. Admissible region based on EMAX, EAVG, EMIN obtained from experiments E BESTFIT shows non negligible error in prediction of elastic response if using E AVGEXPER Need to define a suitable E for the material (statistical B-basis value?) For small beams (2 plies), predictions are too off to be due to normal variability. Different explanations exist, confirmation will follow. If multiple beams of same size are tested, different results are expected. So far only 1 beam per geometry and orientation has been strain gaged & tested. Not possible to measure the variability of the same location strain over multiple specimens. For stochastic approach proposed previously, some agreement (40%) but in others (60%) experimental data falls outside of predicted range. Explanations: 30 runs not sufficient Number of RRVE in each model (312 to 168 depending on size) is not sufficient for convergence 1000 is the suitable value demonstrated previously 42
