A familiar example of an orthotropic material is wood. The roadway sits on an orthotropic deck. Thousands of orthotropic deck bridges are in existence throughout the world. Plagiotropic stems grow in a star- or crown-like pattern around a central orthotropic stem. It was fabricated from weathering steel and has an orthotropic deck. More complex material behaviour like orthotropic material behaviour can be identified by extended IET procedures. In 1985, the bridge was restored using orthotropic steel deck panels. Orthotropic materials have three planes/axes of symmetry. If orthotropic properties vary between points inside an object, it possesses both orthotropy and inhomogeneity. In a HepG2 orthotropic HCC xenograft model in nude mice, bafilomycin prevented tumor growth. The cable-stayed orthotropic bridge is long and wide with a main span of . The new deck contained 82 orthotropic panels, each one measuring by and weighing 20 tons. The Erasmus Bridge has an orthotropic deck for both its cable-stayed bridge and bascule span. Thus the resulting material is anisotropic or, more specifically, orthotropic.
