Engineering Damage Mechanics is deliberately oriented toward applications of Continuum Damage Mechanics to failures of mechanical and civil engineering components in ductile, creep, fatigue and brittle conditions depending upon the thermomechanical loading and the materials: metals and alloys, polymers, elastomers, composites, concretes. For evaluating damage-induced performance of asphalt mixtures by measuring only material properties and fracture properties of each mix component and not by recursively performing expensive laboratory tests that are typically required for continuum damage mechanics modeling. Damage Mechanics presents the underlying principles of continuum damage mechanics along with the latest research. Alkali-Aggregate Reactions (AAR) are chemical processes involving alkalis present in Portland cement, siliceous minerals found in some kinds of aggregates and water (Capra and Sellier, 2001), having as main consequences on concrete the formation of an hygroscopic expansive gel, swelling and cracking. We are pleased to introduce them here. Heterogeneous geometric characteristics and inelastic mechanical behavior were taken into account by introducing finite element modeling techniques and a viscoelastic material model.

Sulfate attack is one of the most aggressive forms of environmental deterioration affecting the long-term durability of concrete structures [1].

Based on continuum damage mechanics theory, an elastoplastic damage constitutive model is presented to describe the mechanical behavior of cementitious materials under compressive stress. His research interests include computational mechanics, finite element methods, solid mechanics, applied mathematics, continuum (damage) mechanics, fatigue analysis, development of analysis/design tools and related computer programming/software. The continuum is regularised through the introduction of gradient terms into the constitutive equations. The most representative method of element degradation approach is continuum damage mechanics (CDM) based FEM, which was widely used for brittle fracturing analysis [43-45]. Implementation of XFEM into available commercial FE code is difficult than standard FEM [99] because additional degrees of freedom are introduced.
