The 13th International Conference on Fracture Fatigue and Wear (FFW 2025)

Abstract: Structures and machine components are nowadays manufactured by additive manufacturing processes. This process dominates the resultant microstructural properties of the manufactured part and hence influences its damage behaviour. An effort is required to incorporate this influence into the existing concept of theoretical and applied mechanics models. At Cranfield, the damage mechanics research group is currently working to explore the mentioned influence with a special focus on structures made by fused deposition-based additive printing. So far extensive empirical testing schemes and computations have been used to analyse the trade-off in the values of printing parameters and the damage resistance of printed structures. Both simple and composite structures are tested under pure dynamic, pure thermal and coupled thermo-mechanical loads. The trade-off is evaluated on simple geometries such as plates and beams and also on composite geometries such as battery pack enclosures and metal-polymer riveted panels. This keynote lecture will provide the highlights of the key results, the complexities in data visualisation and modelling and future work.
