Abstract

Discontinuity Layout Optimization (DLO) is a powerful computational limit analysis procedure which provides a valuable alternative to traditional analysis techniques. For example, compared with finite element analysis methods, a key benefit of DLO is its inherent ability to model singularities in the solution. In this paper recent advances are described, and results for a range of benchmark problems are presented. Advances described include: (i) modelling rotational failure mechanisms; (ii) modelling 3D problems; (iii) modelling non-associative friction. New solutions to the eccentrically loaded footing on a cohesive soil problem (VM and VHM) are presented, showing the evolution of the form of the failure mechanism with changing eccentricity. Additionally, new 3D and non-associative solutions are presented.
