The presentation will cover various problems related to wave propagation in complex media, dynamic fracture of quasibrittle materials, optimization of energy input for fracture, seismic protection. Majority of the results to be presented are based on numerical simulations implementing novel computational techniques and new criteria for fracture and other phase transformations. It will be demonstrated that utilizing the developed approach it is possible to successfully predict initiation, evolution and arrest of dynamic fracture in quasibrittle media loaded by dynamic impact or explosive loads. Other examples will include development of novel seismic protection systems, based on seismic barriers and seismic metamaterials.
