Implementation and validation of a strain rate dependent anisotropic continuum model for masonry

Rafsanjani, Seyedebrahim Hashemi / Lourenço, Paulo B. / Peixinho, Nuno

A newly developed strain rate dependent anisotropic continuum model is proposed for impact and blast applications in masonry. The present model adopted the usual approach of considering different yield criteria in tension and compression. The analysis of unreinforced block work masonry walls subjected to impact is carried out to validate the capability of the model. Comparison of the numerical predictions and test data revealed good agreement. Next, a parametric study is conducted to evaluate the influence of the tensile strengths along the three orthogonal directions and of the wall thickness on the global behavior of masonry walls. ; This work was performed under Project CH-SECURE, with reference TDC/ECM/120118/2010, funded by the Portuguese Foundation of Science and Technology - FCT. The authors acknowledge the support. The first author also acknowledges the support for the Strategic Planning of the School of Engineering from University of Minho.
