Live Parts™ applies forces to simulate the anticipated loads on a part, causing the individual cells within the part to experience strain due to tension, compression, torsion, and shear. This triggers additional cell growth within areas of greatest strain and further strengthens the part. Areas experiencing the least amount of strain experience cell loss, and over time the apparent stress and strain is spread evenly across all the cells within the part.
The forces in Live Parts™ should be considered unit-less “shaping forces” — different from the “analysis forces” applied during material-specific simulations such as finite element analysis (FEA). While FEA analysis explores limits to material properties, Live Parts™ “shaping forces” help create complex geometry that spreads stress evenly across the part. Part geometry created in Live Parts can be tested against specific material properties in any FEA tool, and based on results the “shaping forces” can be scaled to further optimize the design.
