In this paper, a non-orthogonal constitutive model [1] is used to investigate the effect of sample misalignment due to ‘tow meander’, across the initial blank sheet on the shear compliance of a woven glass fabric, as measured using the biaxial bias extension test with various transverse loads applied [2]. The same statistical distribution and spatial correlations of shear angles observed in the woven glass fabric have been automatically reproduced using ‘VarifabGA’ [3]. The effect of realistic tow directional variability is investigated by generating blanks using VarifabGA and then simulating the biaxial bias extension test using the finite element software, Abaqus ExplicitTM. In order to assign the initial fiber orientation to each element in the mesh, a unique element set is assigned to each element. A MatlabTM code 'InitialAngle.m' has been written to produce two input files; the first 'Mat.inp' includes the material property parameters of each element and the second 'Sec.inp' includes the sections of those elements. Finally, a comparison between the experimental and predicted shear compliance shows the effect of tow directional variabilityorientation to each element in the mesh, a method is introduced which involves assigning a unique element set to each element in the mesh. A Matlab code 'InitialAngle' has been written to produce two input files; the first input file 'Mat.inp' includes the material property parameters of each element and the second input file 'Sec.inp' includes the sections of those elements. Finally, a comparison between the experimental and predicted shear compliance shows the effect of tow misalignment on the shear compliance.
