Abstract: We extend the applicability of the embedded unit cell (EUC) method to three-dimensional (3D) fracture problems, which are modeled by the extended finite element method (XFEM). The EUC method is a concurrent multiscale ...

Abstract: The stress-strain behavior of short single-walled carbon nanotube (SWCNT) aggregates is investigated by a novel incremental constrained minimization approach. An AIREBO potential is used to model the interactions within ...

Abstract: A viscoelastic constitutive model for an asphalt–concrete (AC) material that accounts for temperature and material degradation effects is proposed. The model is implemented within a finite-element framework and consists ...

Abstract: This paper first extends a classical solution concerning the shape optimization of a hanging bar. The well-known solution determines the optimal cross section of a homogeneous bar that minimizes elongation under its own ...

Abstract: A new methodology to determine the safety of suspension bridge main cables is proposed in this paper and illustrated by simulating the failure of a corrosion-deteriorated cable composed of 9,061 wires. The approach is the ...

Abstract: A new simplified contact model aimed at capturing the load transfer and recovery length in parallel steel wires, commonly used in main cables of suspension bridges, is presented. The approach is based on placing elastic–perfectly ...
