I am modelling wave propagation in composites (cross-ply) using 2-D layered shell elements for each ply. I need to model cross-section of  composite to  ensure proper loading condition. As the normal direction ( material c- direction) of shell cannnot be changed I have to use transformation matrix to get material properties in the desired direction.The material properties can be seen in the figures. I am not sure if I am defining the model incorrectly or if my material properties is wrong but somehow, I am not getting expected results.  And is there any simpler way to do it without using tranfromation matrix? I have tried all methods ( composite lay-up, defining stiffness matrix) but nothing seems to work. So any feedback would be highly appreciated.<\/p>\n

Thanks<\/p>\n
