Optical fibre design using evolutionary strategies

Steven Manos, Leon Poladian

The design of optical fibres for applications where many performance targets have to be met simultaneously is a non‐trivial process. An evolutionary strategy (ES) combined with an…

A discontinuous finite element method for hyperbolic thermal wave problems

X. Ai, B.Q. Li

This paper presents an unstructured discontinuous Galerkin finite element method for the solution of hyperbolic heat conduction problems that have found a wide range of…

Pullout capacity of spatial anchors

Lidija Frgić, Pavao Marović, Krešimir Tor

This paper discusses the pullout capacity of spatial anchors in soil under applied vertical force. In field tests, the pullout forces were gradually increased and the ground…

A study on the dependency of the interface forces on the FE discretization in nonconvex‐nonsmooth frictional contact problems

E.S. Mistakidis, N.P. Politis

In this paper, the effect of the FE discretization density on the results of both convex and nonconvex‐nonsmooth frictional contact and adhesive contact interface problems is…

Preform optimal design in metal forging using genetic algorithms

M. Poursina, C.A.C. António, C.F. Castro, J. Parvizian, L.C. Sousa

A numerical method for shape optimisation in forging is presented. The goal of the optimisation is to eliminate work‐piece defects that may arise during the forging process. A…

Optimal number and placements of piezoelectric patch actuators in structural active vibration control

Hao Hua Ning

This paper presents an optimal design method of number and placements of piezoelectric patch actuators in active vibration control of a plate. Eigenvalue distribution of energy…
