Orthotropic Single-Surface Plasticity Model for Spruce Wood including the Effect of Knots
نویسندگان
چکیده
In this contribution a brief overview of the development of an orthotropic material model for the simulation of spruce wood under simultaneous plane and transverse shear stresses is given. The model considers an initially linear elastic domain as well as plasticity behaviour including hardening and softening mechanisms at higher states of stress and strain, respectively. The newest feature of the material model is its ability to consider the effect of knots on the strength properties of the different principal material directions of spruce wood.

The goal of this contribution is the development of a plane stress orthotropic plasticity material model for clear spruce wood. Such a model has to consider an initially linear elastic domain as well as hardening and softening behaviour at higher states of stress and strain, respectively. Combining the advantage of a smooth single-surface plasticity model with the identification of distinct har...

In this contribution an overview over a numerical scheme for the crack modelling of spruce wood under tensile loading is given. A material model for biaxially stressed spruce wood with consideration of the effect of knots on the strength properties has been developed. A necessary feature of this material model is its ability to treat cracks by means of the so-called smeared crack concept. For t...

متن کاملExperimental and Numerical Investigation of Timber Structures for the Validation of an Orthotropic Plasticity Model
Although wood is used as a favourite building material among concrete and steel, the mechanical behaviour was not scientifically investigated yet as one would expect. To be able to perform more realistic simulations of timber structures by means of modern numerical simulation methods like the Finite Element Method (FEM), a suitable constitutive material model is required. Such a material model ...
