Solving Mathcad Plot Problem for Yield Simulation Project

[timmay]

As part of a yield simulation project, I have created a datasheet in Mathcad to calculate the principal stresses acting on a tested sample. Due to the fact I have only recently started to use Mathcad (and would like to use it more), I am having trouble plotting a yield locus using its graph functions.

Basically, I have defined two functions for the two principal stresses, sigma subcript 1 and sigma subscript 2. These are functions-of-functions themselves, so that I could merely create data tables with the measured quantities and calculate the stresses as a function of that tabular data.

The problem arises when I come to plot a graph. I would like to plot each obtained value of sigma subscript 2 against the corresponding value of sigma subscript 1. The only way I can think of to achieve this is to put all my calculated values into a matrix.

But how can I plot corresponding components of this matrix against each other?

Sorry for the long winded explanation - I knew I should have used Matlab and just got it over and done with :)

Fortunately, Mathcad does have a feature for plotting data from matrices. It's called the Matrix Plot, and it can be found under the View menu. Once you select this option, you'll be given a dialog box where you can specify the matrix to be plotted, as well as the x-axis and y-axis columns. After you have specified your settings, click OK and you should have a graph of the corresponding components of your matrix.

First of all, I want to commend you for taking on the challenge of using Mathcad for your yield simulation project. It's great that you are trying to expand your skills and utilize this software more. Now, let's tackle the issue at hand.

To plot a yield locus using Mathcad's graph functions, you will need to make sure that your data table is set up correctly. Each column in your data table should represent a different variable, in this case, sigma subscript 1 and sigma subscript 2. The rows should represent the corresponding values for each variable. Once your data table is set up correctly, you can use the "XY plot" function in Mathcad to plot your data.

To do this, go to the "Insert" tab and select "XY plot". Then, select the columns of data that you want to plot (in this case, sigma subscript 1 and sigma subscript 2). Mathcad will automatically plot these values against each other, giving you your yield locus.

If you want to plot multiple data points on the same graph, you can use the "Add to plot" function. This will allow you to select additional columns of data and plot them on the same graph.

I hope this helps you with your plot problem. Remember, it's always a learning process when using new software, so don't be afraid to experiment and try different methods. Good luck with your yield simulation project!
