Hertz Stress

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Hi,

What is the allowable Hertz Stress to check the contact between a Pin and
the Pin Hole?



S_hertz=0.591*sqrt(P/t*E*(D-d)/(D*d)) < S_hertz_allowable ??????

P=force
t=plate thickness
E=modulus of elasticity
D=hole diameter (in the case that hole is greater than 1/32 in. than the
pin diameter)
d=pin diameter


Thank you all,

Glauco
