SS-V: 1180 Stress Concentration in a Filleted Notch

Test No. VS19 Find the stress concentration in a filleted notch when torque is applied.

Definition

The shaft is fixed at one end and a torque of 0.19625 lbf-in is applied on the other end. Shear stress is calculated as 1 psi using the following equation. The units are IPS.

τ_{0} = T c / J

Where,

$c$: $d / 2$
$J$: $π d^{4} / 32$

Model Dimensions: D = 2 in; d = 1 in; r = 0.05 in; r/d = 0.05; D/d = 2

Results

$τ = K τ_{0}$
$K \sim 1.7$

The following table summarizes the stress results.


	Theory¹	SimSolid	% Difference
Shear stress	1.72	1.6885	~1.8
