Numerical study of the size of representative volume element for linear elasticity problem
In the paper, a numerical study of the size of representative volume element for the linear
elasticity problem is performed. The calculations are carried out for three different types of random
microstructures: checkerboard, the Ising model microstructure and Debye microstructure. It is postulated and then verified that there exists a relation between the morphology of microstructure contained in the lineal-path function and the minimum RVE size. It is confirmed, on the basis of numerical examples, that for all the microstructures considered the largest lineal-path can be treated as the size of RVE
