A nonlinear homogenization procedure is presented for deriving macroscopic mechanical behavior of periodic masonry material. In particular, a Cosserat medium is adopted at the macroscopic level, while a classical Cauchy model is used at the microscopic level, where the constitutive behavior of bricks and mortar is known in detail. The nonlinear homogenization is performed developing a Transformation Field Analysis (TFA). A numerical procedure is implemented to solve the evolutive nonlinear homogenization problem based on a predictioncorrection technique. Some numerical applications are performed on the masonry Unit Cell (UC).

Abstract
A nonlinear homogenization procedure is presented for deriving macroscopic mechanical behavior of periodic masonry material. In particular, a Cosserat medium is adopted at the macroscopic level, while a classical Cauchy model is used at the microscopic level, where the constitutive behavior of bricks and mortar is known in detail. The nonlinear homogenization is performed developing a Transformation Field Analysis (TFA). A numerical procedure is implemented to solve the evolutive nonlinear homogenization problem based on a predictioncorrection technique. Some numerical applications are performed on the masonry Unit Cell (UC).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
