Re: Code Interpretation

Hi,

"Pp" is the start value in Pascals

"Sigma min" is the stop value in Pascals and is higher value than "Pp".

This means an interval of "Sigma min" minus "Pp" exists.

Interval is broken into "n" subdivisions. A vector "Pw" is made n+1 entries from 0 to 1000. "j" is used to iterate across the values of "Pw"

At j=0 the value "Pw" is "Pp"

At j=n the value "Pw" is "Sigma min"

Starting at j=0 "j" is increased one step at a time until j=n meaning the stress "Pw" goes slowly from "Pp" to "Sigma min"

Calculations on "Pw" are carried out one increasing value at a time until a test is reached and the loop breaks reporting the value of "Pw" at that time.

"Pw Mohr" is a matrix.  The value "Pw" arrived at in the iteration above is placed in the matrix "Pw Mohr" at the "i"th row and the "k"th column. "i" and "k" are range variables defined earlier.  The iteration for "Pw" is performed for each "i" and "k" automatically getting a different "Pw" each time.
