Shakedown loading optimization under constrained residual displacements—formulation and solution for circular plates

open access: yesJournal of Civil Engineering and Management, 2002
The adapted plate load optimization problem is formulated applying the non-linear mathematical programming methods. The load variation bounds satisfying the optimality criterion in concert with the strength and stiffness requirements are to be identified.

Fatigue Crack Modeling of Railheads Using a Nonlinear Cohesive Zone Model

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Subsurface fatigue crack growth within railheads can be deleterious leading to catastrophic failures in rails. This study aims to model the fatigue crack growth originating at the subsurface level within railheads. Towards that end, a finite element modeling approach is utilized wherein complex crack growth is explicitly modeled using a ...
