Abstract: ABS is widely used in the electronic and automotive industries; therefore, recycling ABS is necessary to reduce carbon emissions. In this work, acrylonitrile-butadiene-styrene (ABS) was studied to evaluate its tensile properties through three cycles of recycling. Tensile tests were performed on both virgin and recycled ABS. For each specimen, values of Young’s modulus, yield strength, ultimate tensile stress, stress at break, strain at break, and Vickers hardness were obtained. Furthermore, FEM simulation using the isotropic elasto-plastic model and the breaking glue model was developed based on the in-plane tensile testing properties and compared with the experimental results to investigate the equivalent stress and strain before the breaking point, focusing on the third recycling step of ABS. The following results were obtained: (i) The in-plane tensile tests showed that the Young’s modulus, strain at break, Vickers hardness, and weight of the specimen tended to increase with each recycling step, while the yield strength, ultimate tensile stress, and stress at break tended to decrease with each recycling step. (ii) The breaking glue model, along with the development of the material model/constitutive equation for the ABS worksheet, was applicable within a certain range of 0.19 ≤ ε ≤ 0.25
