Spinodiod metamaterials are a class of materials with a designed microstructure, which are currently studied intensively. Generally, the properties of metamaterials on the macroscale are adjusted by carefully designing the microstructure. Spinodal structure offer two main advantages. Firstly, these structures consist of smooth, non-intersecting surfaces with nearly zero mean curvature, avoiding stress concentrations on the microscale and enhanced structural performance. Secondly, spinodal designs are non-periodic leading to a broader range of anisotropy, if compared to unit-cell-based, truss-, plate- or triply periodic minimal surfaces. For spinodoids manufactured from aluminum alloys, a novel modeling approach is presented, which considers elasto-plastic material behavior enriched by a nonlocal damage formulation. This modeling strategy allows for prediction of anisotropic elastic, plastic and damage behavior on the macroscale, and is used for evaluating and predicting structural performance of different spinodal microstructures. Numerical examples are shown, which demonstrate the mesh insensitivity, the verification and validation of the proposed framework. Furthermore, simulations on spinodal microstructures are performed to evaluate potential points of failure, see Figure 1.
