I've attached my mathcad document and it explains what I am trying to do.
I have two equations, A and B.
Equation A determines the length of a crack in a material specimen after the specimen has been loaded a distinct number of times. This is based on several variables, one of them being the initial length of the crack.
So after one cycle, I can determine how much this crack grew. I can then determine the residual strength of the material based on this new crack size.
What I need to do, is make a plot that has residual strength (Equation B) in the y axis, and number of cycles (Equation A) in the X axis.
The process would look like this:
1 - Equation A calculates the final crack length in the specimen after ONE cycle (given an initial crack length value).
2 - Equation B takes this final crack length and calculates the residual strength.
3 - The residual strength is plotted in the 2D plot.
4 - This final crack length is then fed back into Equation A to determine how much it grows after ONE cycle.
5 - Repeat steps 2-4 until the residual strengh reaches zero.
How can I do this? I appreciate any help!
Attached is the workbook.
Solved! Go to Solution.
You can/must do a complet calculation one time and than repeat it n time by for example copy and paste equations.
Than you can use the while operator!
Am I getting confused or are you saying N calculates af?
Solve you do not need to solve for af?
Thank you for the help!!! I am going to take a look at this now and see if I can figure out how it is done. At first glance the plots look reasonable.
If I have any questions I will let you guys know.
Do you suppose you could describe what the lines in the program routine mean?
