Weekly Update - Project and Issuances

Hello, blog Readers!

This week, let's talk about the weekly progress done by our team during this fifth week of the Integrator Project.

This week, the team was delegated to issue the material characterization reports. With the results of the previous tests (accordingly to the picture below), we put the data on sheet and analysed it.

Picture 1. Stress-strain graphics, presenting the Test Subjects' behaviour. Legend: CP1 - Red graph, Test Subject 1; CP2 - Blue graph, Test Subject 2; CP3 - Green graph, Test Subject 3; CP4 - turquoise blue graph, Test Subject 4 and CP5 - dark blue graph, Test Subject 5.

The data, however, could not be completely appropriated; there was a great information disparity, as it can be seen in the graphics. The error can remit to any difference in the brass cleaning or foundry parameters, before the test. Added to that, the machine's fault must be considered: the material flow of some test subjects could not be detected, besides the [system's] grasp being not enough to keep continuous stress on the body, therefore invalidating the test of one test subject. Then, the subjects CP1 and CP5 were the considered for the analysis.

With the data set, the maximum diameter of a brass rivet could be 6.667mm. With more advanced calculus, accordingly to the Von Mises' theory and regarding the Project definite specifications, a result of 5.922mm was found for the diameter, according as Picture 2.

Computing also the necessary board length through the pre-defined parameters, a value of 73.177mm was acquired.
The next step, therefore, was to draw the final system at the SolidWorks© software for stress simulation.

Afterwards, the data recorded in the weekly posts contributed to two reports' creation:

•  Material Characterization Report;
• Riveted Joints Project Report.

Those were formatted, added with the SENAI CIMATEC© and TheoPrax© laboratory symbology and ABNT formatation.

That's all for this posting! We hope it was informative about our progresses.

Best regards,
Solarium Engineering Team.
