Displacement controlled tensile test

Click For Summary
Displacement controlled tensile tests focus on maintaining a constant rate of travel while measuring the required load, similar to strain controlled tests. The typical graph orientation for these tests has displacement on the x-axis and load on the y-axis, aligning with standard stress vs. strain graphs found in reference materials. Some older machines may present the graph orientation differently, but the fundamental testing principles remain the same. The discussion highlights the commonality of displacement control in tensile testing and the challenges in finding specific data on this method. Overall, understanding these components is crucial for accurate tensile testing analysis.

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!
 
I need to anneal 5052 aluminum for a home project. Google has given me mixed results on how to do this. Short version is that I'm doing some heavy forming on a piece of 5052-H32 and I'm running into issues with it work hardening. I've tried the Sharpie trick with a propane torch. But I'm not sure this is doing anything. I'm also seeing conflicting opinions whether to quench or air cool. So I'm looking for some expert opinions. (Oven heating is not an option due to size.) Thanks. edit: The...
