Isotropic Material:
This type of material has the same properties in any or all directions and is independent of the coordinate system. An Isotropic material is the most commonly used material type. Mild steel, high strength steel, and aluminum the most commonly used materials in automotive parts, are all isotropic materials.
Orthotropic Materials:
This material type uses three planes (XY, YZ and XZ), having different properties in each of these planes at any given location on the model (Different properties in X-, Y- and Z- directions). Use this type for plate and shell elements. They are used in composites or laminates with oriented fibers. If you use the Orthotropic type, the XC-YC plane should be parallel to the 2D mesh when the material is applied to the mesh.
Orthotropic materials are a subset of anisotropic materials; their properties depend on the direction in which they are measured. Orthotropic materials have three planes/axes of symmetry.

Anisotropic Material:
This type of material has different properties in each direction at any given location which are used for composites or laminates with oriented fibers. An isotropic material, in contrast, has the same properties in every direction.
