Analysis of the effects of density profile on the bending properties of particleboard using finite element method (FEM)

The bending properties of particleboards with various density profiles were analyzed by calculating their modulus of elasticity (MOE) using two-dimensional finite element method (FEM). The calculation was based on the fundamental properties of homo-profile particleboards (board with flat density pro...
