Study on Homogenization Process of Masonry Using Numerical Simulation Based on Periodic Boundary Conditions

The homogenization technique has been used to derive equivalent material properties of masonry for many years, however, very few studies by most previous researchers concemtrated on the strain state of RVE, which is very important to calculate the equivalent material properties in the finite element modeling. In this paper, periodic boundary conditions is established automatically with the python re-development produce in ABAQUS environment, and is used to simulate the stress-strain relationship of RVE in different load cases based on ABAQUS. Equivalent elastic constants is derived and make a contrast to other researchers. The results indicated that the periodic boundary conditions derived in this article is feasible, and a reference is made for the finite element modeling of RVE.
