Cover Story: Crash simulations are required to guarantee low levels of accelerations during impact to reduce damage. Additive manufacturing allows the creation of parts for in situ testing in order to adjust the required force for a given impact configuration. This research shows the repeatability of height compression force–displacement curves of different PLA cubes, showing how a unique stress–strain curve can be used for different sizes and orientations. Simulations of compression and impact are compared to experimental tests and provide a good correlation. A protocol is given to determine the dimension mass and velocity for each cube side. Explicit impact simulations are optimised using mass scaling for time steps, as well as for classic plasticity and foam material models with large strain rates. View this paper
