## Research Interests

Our research interest lies in the mechanics of solids and structures, with applications in structural and mechanical engineering, and geophysics. My group works mainly on fracture mechanics, size effects, and scaling of failure, stability of structures, micromechanics of damage in materials, inelastic constitutive laws, viscoelasticity, and creep and hygrothermal effects in nanoporous materials (chiefly hydrated cements) and hydraulic fracture.

We also conduct research on probabilistic mechanics, plasticity, finite strain theory, numerical methods, and materials testing.

Our research, which emphasizes mathematical modeling, has mainly dealt with concrete, rock, sea ice, fiber composites and soils, and, recently, with braided and woven composites for cars, hybrid joints for ships, rigid foams, shape memory alloys, dry snow slabs, and fracking of gas shale.

Currently we focus on size effect, stability of hydraulic cracks, structural safety, probabilistic analysis of quasibrittle failure, including the tail distribution strength, and predictions of creep and shrinkage effects in concrete structures, with applications to tight gas shale, fiber-polymer composites for aircraft and ships, metallic thin films, reinforced concrete structures and granular materials.
