Nonlinear analysis of RC shell structures using multilevel modelling techniques

Smitha Gopinath, Nagesh Iyer, J. Rajasankar, Sandra D'Souza

The purpose of this paper is to present integrated methodologies based on multilevel modelling concepts for finite element analysis (FEA) of reinforced concrete (RC) shell…

A local remeshing procedure to simulate crack propagation in quasi‐brittle materials

Juha Kuutti, Kari Kolari

The purpose of this paper is to present a new simplified local remeshing procedure for the study of discrete crack propagation in finite element (FE) mesh. The proposed technique…

Multiobjective metaheuristics for frequency assignment problem in mobile networks with large‐scale real‐world instances

Marisa da Silva Maximiano, Miguel A. Vega‐Rodríguez, Juan A. Gómez‐Pulido, Juan M. Sánchez‐Pérez

The purpose of this paper is to address a multiobjective FAP (frequency assignment problem) formulation. More precisely, two conflicting objectives – the interference cost and the…

Formulation of secant and reloading soil deformation moduli using multi expression programming

Amir Hossein Alavi, Ali Mollahasani, Amir Hossein Gandomi, Jafar Boluori Bazaz

The purpose of this paper is to develop new constitutive models to predict the soil deformation moduli using multi expression programming (MEP). The soil deformation parameters…

Multimodal method for linear liquid sloshing in a rigid tapered conical tank

Ivan Gavrilyuk, Marten Hermann, Ivan Lukovsky, Oleksandr Solodun, Alexander Timokha

The purpose of this paper is to derive linear modal equations describing the forced liquid sloshing in a rigid truncated (tapered) conical tank, as well as to show how to couple…

A novel joint diagonalization approach for linear stochastic systems and reliability analysis

Feng Wang, Chenfeng Li, Jianwen Feng, Song Cen, D.R.J. Owen

The purpose of this paper is to present a novel gradient‐based iterative algorithm for the joint diagonalization of a set of real symmetric matrices. The approximate joint…
