A newly developed strain rate dependent anisotropic continuum model is proposed for impactand blast applications in masonry. The present model adopted the usual approach ofconsidering different yield criteria in tension and compression. The analysis of unreinforcedblock work masonry walls subjected to impact is carried out to validate the capability of themodel. 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 alongthe three orthogonal directions and of the wall thickness on the global behavior of masonrywalls.
