Design Aspects of a Ring Tension Test Setup and Evaluation of Transverse Material Stress-Strain Curve of Tubular Components Using FE Analysis



Ring tensile specimens are often used to determine the transverse properties of tubular components due to ease in fabrication and handling. Due to the presence of combined tension, bending, lateral pressure, and friction stresses in the ring tension test setup, it is essential to employ a computational tool in order to evaluate the transverse mechanical properties of these tubes accurately. On the other hand, choice of suitable loading mandrel and loading geometry may facilitate estimation of mechanical properties directly from the tests. In this work, the effect of various types of mandrel design and loading geometries on the load-displacement response of a ring specimen were studied. Finite element analysis with material, geometric, and contact nonlinearities were used in order to simulate the plastic deformation behavior of the specimen in ring tension setup and a novel algorithm was employed to extract the material stress-strain curve from experimental data. In addition, it was observed that a 3-piece mandrel with gage length oriented perpendicular to loading axis produced data which closely fits with the results from finite element analysis.
