Theoretical model and testing method for ball indentation based on the proportional superposition of energy in pure elasticity and pure plasticity

•A proportional superposition-based elastoplastic model (PS-EPM) is used to describe the relationships between the displacement and the load.•An BI-EPS method that determines the mechanical properties of materials is developed.•The stress–strain relations of eleven metallic materials predicted by BI...
