shear modulus of paper ?
shear modulus of paper ?
(OP)
Hi,
I'm trying to design a die punch for paper (0.020-0.025 thk).
Does somebody have an idea of the shear modulus of paper, or any other value that can help me to calculate the force?
Many thanks in advance for any help.
best regards

356/(pi*9/32"*3/16"*2) = 3371 psi
That seems high... something to start with at least.

Balsa wood has a tensile strength of @ 3 MPa (450 psi) perpendicular to grain. This is the closest relevant information I readily found.
