## Research Interests

My interests lie in new interdisciplinary problems of the mechanics of solids and structures, with applications in structural, mechanical and aeronautical engineering, materials science and geophysics. My research group has worked on nonlinear fracture mechanics, size effects and scaling of failure, stability of structures, micromechanics of damage in materials, inelastic constitutive laws, creep and hygrothermal effects in nanoporous materials, chemo-mechanics, failure of fiber composites, hydraulic fracture, impact problems, probabilistic mechanics of quasibrittle structures, plasticity and finite strain, with related numerical methods. Our research, which emphasizes mathematical modeling based on experiments, has been focused on concrete, rock, sea ice, braided and woven composites for automobile crashworthiness, hybrid joints for ships, rigid foams, shape memory alloys, dry snow slabs, fracking of gas shale, probabilistic analysis of quasibrittle failure, especially the tail distribution strength, predictions of creep and shrinkage effects in concrete structures, and applications to gas shale, fiber-polymer composites for aircraft and ships, metallic thin films, reinforced concrete structures and granular materials.
