From: Cross-sectional geometry predicts failure location in maize stalks
An example of the Excel spreadsheet that is provided in the Additional file 1, showing a stalk with five internodes. The user inputs morphological characteristics (viz. distance from canopy, major diameter, minor diameter, and rind thickness of each internode), and the spreadsheet will calculate the section modulus, max-normalized stress of each internode, and the standard deviation of the internodal stresses. The max-normalized stresses are automatically colored from red (maximum stress) to green (minimum stress)
