A new thermodynamic framework for microplane formulations is summarized. A free-energy potential is defined at the microplane level, such that its integral over all orientations gives the standard macroscopic free energy. From this simple assumption it is possible to derive in a unique way consistent microplane stresses and their corresponding integral relation to the macroscopic stress tensor. These new relations are discussed and compared to the traditional approach to microplane model using intuitively defined stresses and the PVW.
