How do i calculate or find out the yield stress of sugarcane?

[a150daysflood]

Hi, from what I know, the crushing force for sugar cane is somewhat similar to pine wood which is about 40 MPA. But since there's water content in it, I need to readjust the yield stress for to crush the sugarcane.

I've tried googling it but couldn't find much useful information. Anyone knows how should I approach this problem?

Thanks for the help!

The crushing stress will be less, but only by testing it at various moisture content will you be be able to find out the results. Wood ultimate strength is also a function of moisture content.
