tensile test simulation

tensile test simulation

RE: tensile test simulation

I am afraid you will need to digitize such data and place it in two arrays, one for time and one for epstot. Or, if the time step is constant, you can spare it and simply use the array index or whatever.

Other than that, you will need to show what you have so far in the program and how you think you would like to have your imposing strain-time curve.

RE: tensile test simulation

(OP)
Thank you for your reply.
If i impose a triangular cycle (figure) i write this:

PARAMETER (pente=1.34d-04,periode=1044.35d0,temp1=522.175d0)
...
DO WHILE (temp.LE.periode) ! DEBUT BOUCLE TEMPS

IF (temp.LE.temp1) THEN
pendefo=pente
ELSE IF (temp.GT.temp1) THEN
pendefo=-pente
END IF

c Déformation totale IMPOSEE 'depstot'
depstot=pendefo*deltat
.....

but with the previous cycle i don't know how to add the array because 'depstot' must be a real ?

RE: tensile test simulation

I don't see anything regarding time in your code.

Also, I don't see anything triangular...it looks more like a square wave that goes from +pente to -pente.

I think you need to put together a y=mx+b kind of equation where x is actually time t and y is strain...you need two equations of those, one going up and one going down, etc.
