Shear Stress Deflection
Shear Stress Deflection
(OP)
Does anyone have any references on calculating deflection due to shear stress? I am looking for deflection due to uniform load, simply supported beam for a sandwich panel (aluminum skins with EPS core). Thanks for any input.






RE: Shear Stress Deflection
Delta= (P*L)/(A*G)

Hope this helps.
RE: Shear Stress Deflection
delta = integral (M*m/E*I) dx + integral (V*v/G*A')dx + sumation (NnL/AE)
where M, V and N are the internal stresses due to the real, exteranally appiled loads
& m,v,n are the internal stresses due to the stress caused by the virtual load.
A' is the shear area
A is the cross-sectional area
L is the length
E is the modulas of elasticity
G is the shear modulas
delta is the deflection times the unit load applied

Also, steve1 shear stress is not insignificant in this case because of the EPS foam core which has a very low G (shear modulus). And, Mattman, you're right except missing some factors which change for loading type, end conditions, and cross section of the member. Just some info. Thanks again.
