Abstract: This educational article is focused on a simple geometric explanation of basic concepts of large deformation theory in an undergraduate curriculum in materials pressure forming. The paper provides a unified original introduction to macroscopic rotation and rotational inhomogeneity concepts for technical students working with soft modelling materials in laboratory classes. The original author's approach to an engineering interpretation of theoretical and experimental laboratory research work uses only a simple geometric computational approach and does not involve calculus techniques. This mathematics-free explanation is easily understandable and appropriate for a wide community of technical students with any level of preliminary knowledge. The proposed novel educational approach is an interesting enhancement of existing materials curriculum for creative student-centred training of technical specialists both in metal forming and polymer pressure forming.

Keywords: engineering education; material forming education; materials science education; theoretical-experimental laboratory research work; initial circular gridlines; large deformation; macroscopic rotation; rotational inhomogeneity; plasticine models.
