Numerical analysis of mechanical behavior of softwood: bilinear elasto-plastic orthotropic model
Original language description
Finite element method (FEM) is one of the most effective approaches for the virtual assessment and prediction of behavior in timber structures. Norway spruce is considered as desired model wood because of its frequent use. The complex modeling of behavior includes assumptions of orthotropicity and non-linear stress-strain response. The aim of the study was to determine the elasto-plastic material characteristics of compression tests parallel and perpendicular to the grain and three-point bending in compliance with the relevant test standards. Elasto-plastic material model was the basis for the finite-element (FE) analyses with the input of experimental data. The elasto-plastic material model with non-linear isotropic hardening was applied based on the Hill yield criterion in regions of uniaxial compression. The material characteristics were optimized and validated by means of general FE models under the same conditions as applied for the experiments. A good agreement was found between numerically predicted and experimentally measured data. The proposed elasto-plastic material models are capable for predicting of the ultimate strength, and therefore could contribute to a more reliable design of wood structures and their performance.
