The deliverable of this Liverpool John Moores University project was to create a Finite Element (FE) simulation of the impact on one of a Scott Safety helmet HC300, which will ultimately be used as a model to verify against actual impact test results that are currently undertaken. The simulation has the scope for improving future designs and testing, allowing for adjustments to the model to potentially save material and critically save expenditures on manufacturing as well as furthering safety equipment technology. The modelling and simulations are compliant with British Standards (BS EN 397:2012+A1:2012) testing procedures for a safety helmet. An explicit impact and an explicit spike test simulation have been modelled and analysed in ABAQUS. The methodology of such modelling has been detailed within a full report, with reasons as to what steps were taken in the advanced modelling of the helmet testing conforming to British Standards. Experimental analysis has been completed at Scott Safety, which verifies the modelling completed in the FE software. Appropriate material testing and analysis have also been detailed, with an understanding of the process of attaining raw test data and subsequently applying this data into ABAQUS. The FE models have been validated through energy transfer, plastic deformation and experimental testing, this was to ensure all results obtained are true and verified for potential future work or industrial application.
