| Popis: | This paper presents an empirical model predicting penetration resistance forces (PRF) imposed on nails when penetrating plywood samples at quasi-static velocities (20–500 mm/min range). The formulation covers various nail geometries and sizes and three plywood types. A universal testing machine was used to drive the nail into the wood samples at constant speeds. The machine measured PRF as a function of the position. The analysis reduces the studied factors to dimensionless parameters. More than 200 experiments were conducted over the parameter space, and the final formulation derives from regressions. Test cases showed an overall precision of PRF prediction above 89%. |
