The current study presents a simulation model comprising an input generation method, micromechanical model, and a method minimizing the boundary artifacts through micropolar elasticity, also known as Cosserat elasticity. The present input generation method provides the geometric description of the actual cellular materials in two-dimensional space including the cell wall thicknesses, cell connectivity, vertex, and center coordinates. The gathered data are then used to mimic the mechanical behavior of actual cellular material in the virtual environment. As a case study, microscope images of Norway spruce (Picea abies) were used to form the near-exact geometry to be used as the solution domain for the micromechanical model. Thereafter, simulation experiments were conducted to understand the size effect and measurement domain selection on the in-plane elasticity of wood-like cellular materials.
