Material System Concept Definitions

• A Material System (MS)

  • is a 1-D, N-layered set of material compositions, with boundary conditions at the surface and bottom layer.
  • It provides a construct that can be assigned to vertices or texels or solids

• A Layer

  • has a thickness, and is comprised of 1 or more materials, each of arbitrary aggregate mass % in the layer. If particulate in nature, a material’s median characteristic particle diameter is specified.

• A Material

  • is a substance uniquely defined by a set of physical property values and associated property tolerances that are assumed homogeneous throughout
