Modeling Moisture-Induced Damage in Asphalt Concrete
Moisture damage in Asphalt Concrete (AC) is not new but an unsolved problem. For decades laboratory studies have been conducted on both loose and compacted mix to understand the effects of moisture on the AC damage. Adhesive and cohesive damages are the two major types of damages occur inside the …

Analytical Modeling of the Mechanics of Nucleation and Growth of Cracks
… laws thermodynamically consistent with damage mechanics are postulated that relate the interfacial tractions to the displacement jump. An exponential function is used for the constitutive law such that it satisfies a multi-axial stress criterion for the onset of delamination, and …

Dynamic Fracture of Adhesively Bonded Composite Structures Using Cohesive Zone Models
… surface material is implemented through an interface element, which is incorporated in ABAQUS using the user defined element (UEL) option. A procedure is established to formulate a rate dependent model based on experiments carried out on compact tension test specimens. The rate dependent …

Computational Micromechanics Analysis of Deformation and Damage Sensing in Carbon Nanotube Based Nanocomposites
… discrete locations using sensors and detecting damage using techniques such as X-ray, microCT, acoustic emission, impedance methods etc., primarily employed at specified intervals of service life. There is a need to develop materials and structures with self-sensing capabilities such that …
