Caracterização mecânica e simulação do comportamento mecânico da poliuretana derivado do óleo da mamona enriquecido com 10% de carbonato de cálcio

Abstract

Increasingly, they are seeking solutions to environmental problems and shortage of raw materials for use in daily life. Thus, obtained from renewable materials have been studied for a possible replacement of currently marketed. The polymers have wide application due to their properties and biopolymers meet the needs arising from the use and disposal exacerbated. In this context, the polyurethane becomes an interesting option, but for its proper application, it is necessary to characterize it and get their mechanical behavior. In this work, we carried out analyzes in order to compose a study of polyurethane enriched with 10% calcium carbonate through monotonic testing of tensile, compression and bending simulation set in computer software. Models of Drucker-Prager were applied, and the von Mises criterion with Viscoplasticity. Finally, the experimental results obtained by computer analysis were compared and the validation thereof was discussed.
