Our client from the additive manufacturing industry approached us to assist in the development of an advanced material properties library of various lattice structures of different shapes and patterns aiming to facilitate the material selection process for potential applications and clients.

​

By incorporating lattice structures into the design of a component or assembly allows to overcome complex engineering challenges in a structurally effective way.

​

We designed and performed a series of experiments including low and high rate compression, tension, 3p and 4p bending, torsion and drop tests to determine the behaviour of various samples, including stress-strain curves, non-linear rate dependency, yield and ultimate strength, modulus of elasticity, shear modulus etc.

​

We also simulated these tests using FE models and our bespoke inverse FE modelling algorithm to derive bulk material properties of each lattice shape and facilitate future modelling studies.
