FIELD: physics, measurement equipment.
SUBSTANCE: invention refers to methods for material mechanical properties determination by indentation into the sample surface to a predetermined load, namely to methods for static Young's modulus (hereinafter - modulus of elasticity) determination. Essence: experimental indentation and computer modeling of indentation by the finite elements method are combined, the elasticity modulus of the particle corresponding to a zero difference in the calculated and experimental indenter penetration depth is determined, the modulus of elasticity of the same particles is determined by the Oliver-Pharr method. The elasticity modulus value, obtained by calculation by the Oliver-Pharr method is compared to the value obtained from the stage of numerical studies, the arithmetic mean of the elasticicity modulus of the investigated particle is determined.
EFFECT: invention enables elasticicity modulus determination for micro- and nanoparticles material of any shape.
