Abstract

We present a new computational model for predicting the eﬀect of blast loading on structures. The model is based in the adaptive coupling of the ﬁnite element method (FEM) and the discrete element method (DEM) for the accurate reproduction of multifracturing and failure of structures under blast loading. In the paper we brieﬂy describe the basis of the coupled DEM/FEM technology and demonstrate its eﬃciency in its application to the study of the eﬀect of blast loading on a masonry wall, a masonry tunnel and a double curvature dam.
