Simulation of Abaqus Traction

Simulation Generality

Hello

I do a simulation of a tensile test on abaqus. I compare a simulation done on abaqus with a real tensile test.

I take 1/4 of a test tube to do the simulation. I apply a velocity to a point called "master" and then I assign an amplitude to this velocity. I would like to know what is the relationship between speed and this amplitude? The speed is equal to 10MPa/s. I don't know if we apply a speed of 10 directly to the point, or if we start little by little until it stabilizes at 10? You will find the specification of the test in pictures.

Also, we used "*TIME POINTS" I don't know what it's for if you can enlighten me this point too.

PS: I have an INP file handwritten by a colleague, I'm just importing what he did and trying to understand.

You will find attached the inp file where you can see the speed at the "master" point, the amplitude used as well as the *TIME POINTS. A doc to explain the test a bit.

Thank you in advance for your help, I'm turning to you because I have no idea how to get there.

THANK YOU

Here's my INP file.

Thank you

Hello 

The amplitude manages precisely how the load is applied.

You can choose to apply the entire load at the beginning of the step, or to apply it linearly during the step, or to apply it according to a predefined amplitude curve like "smooth" which allows you to apply the load first lightly, then faster and faster and then again gently as you approach the maximum load. 

On the other hand, according to the image in the documents you have set a displacement of the node and not a speed, so your speed will be given by this displacement in relation to the duration of the step.
