May 01, 2012The non-significant effect of bending direction on the stiffness demonstrates that the embedding of the proximal 5 mm of the tibia in cement removed any potential effect of this buckling region. Desiccation also had a significant effect on the bending strength of the tibia samples ( F 2,25 =41.593, P 0.001).

"The buckling case study is pretty much spot on. As you may or may not know, we are fairly new to the adhesive lamination process, with our first line installation in spring 2015. Probably the first major learning for us was the buckling issue, which as you know is not a typical extrusion lamination issue.
