Impact Strength (mild steel tubing)

  1. Mar 15, 2007 #1
    I need to calculate what percentage increase in impact strength I will get by inserting a 1" OD round tube with .083 wall inside a square 1 3/4" width tube with a .059 wall. Both are mild steel, ERW tubing. Check attached file for diagram.

    I can find out the tensile strength, if that is needed in the calculations. Can anyone help in how to go about this ?
