IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThis study investigates the applicability of a stress-based approach to multiaxial fatigue strength assessmentof fillet-welded tubular T-joints, used in the so-called ‘‘H” component of an agricultural sprayer.Experimental strain measurements on such a structural component under sprayer service conditionshave been performed. A finite element analysis of the component is herein developed under linear elastichypothesis. Finally, a stress-based critical plane criterion is applied to several material points located inthe proximity of the intersection between the end of a brace and a chord of one above-mentioned T-joint,where crack nucleation is experimentally observed.
