A boundary element method for axisymmetric potential problems with non‐axisymmetric boundary conditions using fast Fourier transform

Ch. Provatidis

This paper presents a methodology, based on the fast Fourier transform (FFT), that improves prior established techniques to solve axisymmetric potential problems with…

A symmetric Craig‐Bampton method of coupled fluid‐structure systems

Johannes Wandinger

A symmetric Craig‐Bampton method of coupled fluid‐structure systems is developed. The reduced matrices of the substructure have the same features as those of conventional…

Generation of ground structures for 2D and 3D design domains

Ole da Silva Smith

Introducing the concept of a design domain to truss topology optimization, this paper presents an algorithm generating geometrically admissible ground structures on possibly…

A D/BEM approach to the transient response analysis of elastoplastic plates with internal supports

C.P. Providakis, G. Toungelidis

A boundary element method for solving problems dealing with the dynamic analysis of thin elastoplastic flexural plates of arbitrary geometry and conditions inside the domain is…

A 24 d.o.f. four‐node flat shell finite element for general unsymmetric orthotropic layered composites

Albert A. Groenwold, Nielen Stander

The constitutive relationship of a four‐node flat shell finite element with six degrees of freedom per node and a modified five‐point quadrature, previously presented by the…
