A Proposed Method to Evaluate the Effect of Changing the Kerfing Parameters upon the Static Bending Behavior of Flexible Plywood Panels Cut by Laser

The purpose of this paper is to propose a method for testing the effect varying kerfing parameters, on flexibilization plywood panels indoor applications. evaluation was made by comparisons change in MOE, MOR, and maximum deflection, between flexibilized non-flexibilized specimens subjected static bending tests based EN 310. In order prevent problem sliding from supports occurring specimens, standard were modified adding frame subjecting just their central rail. Framed poplar plywood, 8 mm thick, laser cut with rigid rail, taken as reference flexible kerfed These had lengths area 50, 70, 90, 110 two dimensions pitch, 6 10 mm. Very good correlations found deflection length area, both values kerf which proves sensitivity proposed changes input parameters. could further serve mathematically model flexibility panel selecting appropriate data.
