Homework Statement



Ok, so in a lab I was preforming Izod impact tests on notched polymer specimens.
To complete my calculations I need to determine the correct cross-sectional area to use (Which is baffling me as the simple things usually do)

The sample was loaded with the notch facing the direction of the pendulum.

Homework Equations



Width 12.97mm
Thickness 5.87mm
Length 62.61mm

And the Notch is 2mm deep at an angle of 45°



The Attempt at a Solution



So I haven't got far with my attempts at the problem because I'm liteally clueless at where to begin and how the notch will effect the cross sectional area. Any help or tips will be greatly appreciated!

I don't get involved witht the actual impact testing method and analysis...I simply specify that such tests should be done (at the mill, if steel, which more typically uses Charpy V-notch testing) in accordance with established testing standards.
I would surmise that the cross section area at the apex of notch is the remaining (net) cross section area in the shear plane after removing the notch area. Make sure you calculate this correctly based on which face the notch is on.
