Multiresolution molecular dynamics approach on parallel computers has been used to investigate the structural properties and mechanical failure in microporous silica. Critical behavior at fracture is analyzed in terms of pore percolation and kinetic roughening of fracture surfaces. Crack propagation in amorphous silicon nitride films is investigated, and a correlation between the speed of crack propagation and the morphology of fracture surfaces is observed.
