Desenvolvimento de um dispositivo de tração biaxial para ensaios mecânicos de materiais.

Abstract

The present study, which was documented in this paper, sought to develop a device for conducting a biaxial traction test using the solutions presented in the literature. Initially conducted a study that was condensed into an information frame and subsequently extracted the data that served as the basis for the project. Applying the design methodology and analyzing the initial data, a device to be coupled to a conventional traction machine was chosen due to its ease of application. Following the methodology, had the stage of informational design, conceptual design, preliminary design, detailed design, fabrication and testing. The prototype test was performed with a cross-shaped test piece according to ISO 16842: 2014. It is possible to develop a biaxial test device based on the mechanism presented by Rohr, Harwick and Nahme to be coupled to a universal traction test machine and using a cruciform test body.
