Wood fiber modelling using stochastic models

Abstract

Various kinds of materials such as iron, wood, and concrete are very useful in human life. For example, the wood fiber can be used in building construction such as wall, roof, floor, as well as automotive interior. The design process of such materials is therefore still continuously researched and developed in order to create high quality products. To avoid excessive costs, it is essential to establish a non-destructive design technique of the macroscopic material. In this paper, the design technique of fibrous material using computer based modelling (virtual material design) as the realization of stochastic models will be investigated. In this model, the fiber can be stated as either a dilated curved lines, a chain of balls or cylinders with different cross-section. In this research, we will focus to investigate the image of Medium Density Fiber (MDF). It will be modelled as cylinders using the Poisson cylinder process with a rectangular cross-section. We also use Euler rotation and β-distribution to determine the position and orientation of the fibers in the system. Simulation software was conducted to verify the model. The result showed that the realization of fibers model is similar to the image of the wood fibers sample.
