Research Interests

Our research interest lies in the mechanics of solids and structures, with applications in structural and mechanical engineering. Our 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 cements).

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 composites for cars, hybrid joints for ships, rigid foams, shape memory alloys and dry snow slabs.

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