Purpose: This study aims to provide a systematic evaluation of the EVA application in orofacial protectors while focusing on sports. Design/methodology/approach: The research comprises a numerical analysis. During experimental tests, EVA was analysed in special more specific studies about its influence on the mechanical behaviour of EVA were performed. In the numerical analyses of the EVA orofacial protector, the studies focused on its effect in the zygomatic bone protection, in a simplified geometry. Findings: According to the experimental and numerical results from a systematic study of EVA, its application to orofacial protection can be considered satisfactory. Research limitations/implications: The limitations for this research is the complex geometry of the face, number of materials and parameters involved in this study. Practical implications: For facial protection, a better performance is obtained with a combination of rigid and soft EVA material. Particularly for the zygomatic bone, a 3 mm thick plate of soft EVA overlapped by a 1 mm thick plate of rigid EVA is indicated. Originality/value: The studies made for this researchers group show that the EVA use in facial protection for sports is effective.
