Displacement controlled tensile test

Click For Summary
SUMMARY

The discussion focuses on the displacement controlled tensile test, emphasizing the importance of understanding the x-axis (displacement) and y-axis (load) components of the results. It clarifies that displacement control is the most common method used, contrasting it with strain control and load control. The graphing orientation for both displacement and strain controlled tests is typically identical, with displacement on the x-axis and load on the y-axis, aligning with standard stress vs. strain graphs. Reference to the ASM International 2004 publication highlights the variations in graph orientation encountered in different testing machines.

PREREQUISITES
  • Understanding of tensile testing methodologies
  • Familiarity with stress vs. strain graphs

Hi, I'm looking for the result of displacement controlled tensile test.
I want to know about the x-axis component and y-axis component of the result, not the whole data.
I read about some articles about these and they said displacement control is most common.
I've searched a lot but all I found was strain control or load control.
If anyone know, kindly share at here.

Strain controlled and displacement controlled tests are identical in that the rate of travel during the test is maintained constant throughout the test and the required load is measured; as opposed to a load test where a uniform rate of loading is applied and the displacement is measured.
For the majority of tensile testing machines the graphing for both methods is identical with x as displacement and y as load; and, this is the preferred orientation because it is the one that corresponds to essentially all stress vs strain graphs presented in texts and reference documents.
On the other hand, many years ago I used one machine on which this graph orientation was reversed; and, the ASM International 2004 Tensile Testing, Second Edition (#05106G) includes an figures with both orientations.

Thank you very much, those are really helpful!
