Three different materials can be set up in MSC Apex Generative Design:
Isotropic Material
The properties of Isotropic material are uniformly in all directions. Therefore, only one Young's modulus, one Poisson’s ratio and one Tension (Tensile) Strength is needed.
...
3D Transversely Isotropic Material
The properties of 3D Transversely Isotropic material are directional dependent. One direction (axial / build direction) differs from the two other in-plane directions. The x-axis is always the build direction, the y- and z-direction are the in-plane directions. As an input the Young's modulus for the build direction as well as for the in-plane directions (Ey=Ez) are needed. Furthermore, the Shear Modulus and the two Poisson’s ratios for in-plane and axial are desired. All further necessary values are calculated in the background.
...
Optional the Compression Strength can be set up. With the directional dependent Tsai-Wu Failure Criterion the difference between tension and compression can be considered besides the directional dependency.
...
3D Orthotropic Material
The properties of 3D Orthotropic material are directional dependent. For every main axis a different Young's modulus is needed as well as Shear Moduli for all planes and the Poisson’s ratios.
...
Optional the Compression Strength can be filled in. With the directional dependent Tsai-Wu Failure Criterion the difference between tension and compression can be considered besides the directional dependency.
