Yes the material input was done after defining the element type and material model. I was able to get it to solve without any errors by defining shear modulus in the material properties.

Anisotropy and Isotropy. In a single crystal, the physical and mechanical properties often differ with orientation. It can be seen from looking at our models of crystalline structure that atoms should be able to slip over one another or distort in relation to one another easier in some directions than others.

Box girders are usually considered for footbridges only for spans over about 30m, and most box girder footbridges adopt an all-steel configuration. The advantage in using an all-steel configuration is that the whole cross section, including parapets, can be fabricated at the works for delivery and erection in complete spans; the weight of such spans is modest and easily handled by a mobile crane. Tensile yield strength is the maximum engineering stress in psi (or Pa) at which a permanent non-elastic deformation of the thermoplastic material begins.
