Shell Property

Shell property is a physical property assigned to surface elements.

A shell property references a material assigned to the surface part and describes a thickness associated to this surface part. A shell property is associative to the geometry this property points at.

The input and output characteristics are:

  • Input:

    • Material

    • Thickness

  • Output:

    • Stress

    • Strain

    • Point force vector

    • Point moment vector
    • Stress Von Mises
    • Elastic energy
    • Elastic energy density
    • Estimated error
    • Curvature
    • Transverse shear strain
    • Transverse shear stress

Those characteristics can be expressed at the given positions in the elements and in different axis systems:
