Ring Hoop Tension Test for yield strength estimation: Numerical analysis for a novel correlation method and applicability for mechanical testing of tubes and pipes

The tubes and pipes manufacturing industry characterizes the mechanical properties of their products with a wide selection standards, but most them are qualitative testing methodologies. To estimate from quantitative point view there limited options in standards. In that sense, standard tensile test is preferred alternative by manufacturers, this option limits estimation for longitudinal direction tube–pipe product. Particular efforts have been made to design an procedure characterize hoop tubes. Ring Hoop Tension Test (RHTT) was designed fill gap, it shows limitations related required tooling influence frictional contact between ring specimen. nuclear industry, Small (SRT), miniature derivated RHTT, has investigated recent years. investigation, novel RHTT overcome SRT new implemented yield strength pipes. Numerical FEM simulations were performed reach optimum method specific geometry pipe geometries RHTT. A set hypothetical materials perform these analyses, taking into account Young’s modulus, proportional limit, hardening coefficient (based on Ramberg–Osgood law), presence Lüders bands straining. verify results obtained numerical analysis, experimental tests (standard RHTTs) metallographic analysis aluminum Al 6063 T6 copper C12200 R360 tubes, showing capability optimized anisotropic
