Nonlinear Finite Element Modeling of Red Meranti Compression at an Angle to the Grain

Abstract

In an orthotropic material on its mechanical properties. The aim of this research numerical simulation using the compression strength of angle to the grain rang ing analysis were obtained from clear spe the numerical results, various cross grain specimen s were tested under uniaxial compressive stress. It has been shown in this study that distortion energy of an compressive strength at proportional limit for cros s grain specimens. Compa rison with the experimental results show 12° and 80° the FEA predict experimental results. Compared to compressive strength at a value, ranging from 13.2% to 30.5 incorporating Hill's yield compressive strength at an angle to the grain. orthotropic material , the grain angle has a significant influence mechanical properties. The aim of this research was to perform a numerical simulation using a nonlinear finite element analysis (FEA) to obtain strength of the Red Meranti ( shorea spp. ) timber species at an ing from 12° to 80°. The material properties needed fo r the obtained from clear spe cimen tests. To investigate the validity of the numerical results, various cross grain specimen s were tested under uniaxial It has been shown in this study that an FEA based on the an orthotropic material can be used to obtain the compressive strength at proportional limit for cros s grain specimens. Compa - experimental results show ed that for a cross grain angle between predict ed the strength to be 9.4% to 33.6% lower than the Compared to using Hankinson's formula to predict the compressive strength at a cross grain angle, using the FEA always gave a low er ranging from 13.2% to 30.5 %. Based on these results, an FEA yield criterion is a conservative method for predicting compressive strength at an angle to the grain. ; FEA ; grain angle; Hill's yield criterion; red meranti.
