Modelling of Stress-Strain States of Nanomaterials Created by Multiple Plastic Deformation

Popis výsledku v původním jazyce

The article deals with the identification of changes in the elasticity under compression exerted on the material during intensive plastic deformation using the ECAP method, and specifically on the material of the aluminium alloy EN AW 6060. The results of direct measurements were compared with the results of indirect measurements (i.e., with the results predicted and calculated). During each extrusion, the extrusion forces were measured directly depending on the lengths of the extruded sample, and then the mechanical work applied to the volume of the extruded sample as extrusion stress of the AlMgSi 0.5 material were evaluated. There are many methods available for evaluating the Young's modulus, but the proposed method is especially suitable for the material samples processed by the ECAP process. The research aimed mainly at evaluating the bulk modulus, and then the most accurate estimation of the Young's modulus after each extrusion. When Poisson's ratio and bulk module is known, the Young's modulus for samples of metallic materials can be evaluated using the relationships between elastic modules.
