“…The second is the production of polymer pipes, which causes a significant difference in the mechanical behavior between traditional tensile test specimens from basic materials and the final product of plastic pipes [1]. Due to the long distance and complex terrain of pipeline transportation, high toughness, fatigue resistance, corrosion resistance, and fracture resistance are necessary properties of pipeline materials [2].…”

Data on the strain and stress status of the pipe in the circumferential direction are required for various pipe manufacturing procedures (e.g., in the oil business, the process of manufacturing seamless pipes with a conical shaft). The aim of this study is to develop a procedure to determine the strain and stress behavior of Pipe Ring Tensile Specimens (PRTSs) in the hoop direction, as there are a lack of official standardized methods for testing PRTS. This paper discusses the application of the Digital Image Correlation method for testing plastic PRTSs. PRTSs are tested using a specially designed steel tool with two D blocks. A 3D-printed PRTS is placed over two D-shaped mandrels, which are fixed on a tensile tool and tensile testing machine. The strain evolution in the gage length of the specimens is captured using the three-dimensional Digital Image Correlation (3D DIC) method. To check the geometry of the cross-section of the PRTS after fracture, all the specimens are 3D scanned. For the study, six groups of PRTS are analyzed, consisting of three filling percentages (60, 90, and 100%) and two geometry types (Single and Double PRTS). The results show that the type and percentage of filling, as well as the method of printing, affect the material behavior. However, the approach with the DIC system, 3D printer, and scanner shows that they are effective instruments for mapping complete strain fields in PRTS, and thus are effective in characterizing the mechanical properties of pipes.

“…Numerous research has examined how side grooves affect deformation conditions for grooved side samples as well as fracture behaviour, crack initiation, stress, and strain [10][11][12]. Nevertheless, the impact of different side-groove shapes received just small attention in published studies in this area.…”

Aluminium alloy 6061 is known for its superior mechanical characteristics, which include lighter weight properties, high specific strength,and simple fabrication. Hence, they are widely used to reduce the weight of vehicles as structural parts. Aluminium alloy 6061 issubjected to high velocity and various forces in the courseofan accident. Hence, understanding the impact properties of aluminium alloys is critical. The impact of side groove shapes on the shear lip development of aluminium alloy 6061 was examined in this work. The shapes of the side groove in this study are V-shape, U-shape,and square-shape. By simulation using Abaqus software, the Charpy impact test was conducted todetermine the shear lips ratio, energy absorbed, displacement and force. It was found that the V-shape side groove shape has the lowest absorb energy as compared to the U-shape and square-shape. The low absorbed energy indicates that the behaviourof the sample test is in a fast-moving brittle fracture. Furthermore, it can be observed that the shear lips for V-shape and square-shape have the lowest ratio of shear lips compared to the U-shape of the side groove. The lower a material's shear lips ratio, the more likely it is to become brittle. In conclusion, when the shear lips ratio is low, it will tend to be low ductility of aluminium alloy 6061, the energy absorbed is low, and the impact of the force is also low.
