Do fillets reduce stress
WebThe FEA analysis showed that the joints where the six heavy spokes link up to the hub and to the outer rim are all critical areas. The fillet at those junctions was increased to a ―" radius to reduce the stress … • Stress concentration is a problem of load-bearing mechanical parts which is reduced by employing fillets on points and lines of expected high stress. The fillets distribute the stress over a broader area and effectively make the parts more durable and capable of bearing larger loads. • For considerations in aerodynamics, fillets are employed to reduce interference drag where aircraft components such as wings, struts, and other surfaces meet one another.
