| Numerical experiments on the compression test of copper have been carried out via finite element analysis. A range of the friction coefficients has been considered between the platen and specimen for varying ratios of the height-to-diameter of the specimen. The ratios of the measured stress-strain curve under a friction-free stress (σ ; the input property) to the measured stress-strain curve under a frictional condition (σ) have been quantified, followed by designing a phenomenological friction-compensation model: σ/ = f(μ) for a given height-to-diameter ratio of the specimen. The values of the fitting constants for the designed model are provided for copper. The model and the provided constants are verified to be reasonable in predicting the stress-strain curves measured under a frictional condition for a range of height-to-diameter ratios of the specimen not only for copper but also tantalum and Al6061-T6. |
