Automated procedures for Boolean operations on finite element meshes

J.L. Graysmith, C.T. Shaw

Develops a method which performs Boolean operations on two unstructured arbitrary meshes. Deletes the overlapping or interfering elements of two individual meshes and creates a…

Structural seismic response to inhomogeneous random field

Jiahao Lin, Jianjun Li, Wenshou Zhang, F.W. Williams

Proposes a new approach for analysing the stationary random response of complex structures located in a non‐homogeneous stochastic field. The approach is a kind of complete CQC…

An alternative linearization technique

Keith M. Mueller, Scott A. Burns

The numerical treatment of non‐linear engineering phenomena often involves some sort of mathematical simplification. In many cases, the system under investigation is linearized…

Optimal (distributed or boundary) control of the vibrations of continuous systems solved numerically in a space‐time domain

A. Bazezew, J.C. Bruch, J.M. Sloss

Presents numerical algorithms which easily solve both optimal distributed and optimal boundary control problems in a space‐time domain. Analyses two simple cases of continuous…

On the formulation of enhanced strain finite elements in finite deformations

S. Glaser, F. Armero

Presents recent advances obtained by the authors in the development of enhanced strain finite elements for finite deformation problems. Discusses two options, both involving…

Dynamic stability of elastically constrained beams: an exact approach

C.E. Majorana, C. Pellegrino

Finds the regions of dynamic instability of elastic beams constrained at the ends by means of translational and rotational elastic springs, using the equation of boundary…

Iterative mesh generation for FE‐computations on free form surfaces

Leif Kobbelt, Torsten Hesse, Hartmut Prautzsch, Karl Schweizerhof

Presents an interpolatory subdivision scheme to generate adaptively refined quadrilateral meshes which approximate a smooth surface of arbitrary topology. The described method…
