FINITE ELEMENT ANALYSIS AND MODIFICATIONS IN PLYWOOD STRUCTURE TO ENHANCE IT'S STRENGTH

Ajit Krushnarao Surve


This paper explains the plywood. The available sizes, stresses developed, force distribution of plywood in different conditions. It outline the mechanics of plywood, and calculations that relates the in-plane strain and curvature of a plywood to the forces and bending moments imposed on it. As plywood are not suitably used where temperatures are higher, and it is a brittle material so temperature effect and viscoelastic response is not considered. The analysis is done by using Ansys software. Analysis is done by using softwoods, and it is observed that the plywood are less strong in the radial or bending. To improve its strength various combinations are done by using hardwood, softwood and ABS and the result obtained is 27.5% decreased stress developed in combination 3. Minimum deformation is observed in combination2. And minimum strain intensity in combination2 and 4. By making use of polymers like ABS it is also possible to change the properties of plywood.
