tensile test simulation
tensile test simulation
(OP)
Hello,
i would like to simulate tensile test under strain's control with Fortran (i.e i impose strain and then i calculate the corresponding stress state). The curve strain-time that i want to impose is given by the attached file.
How can i write this cycle with Fortran?
Thank you

RE: tensile test simulation
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.

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 ?

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.
