We present a computational framework for analyzing thin shell structures using the finite element method. The framework is based on a mesh-dependent shell model which we …
Nowadays, engineers possess a wealth of numerical packages in order to design civil engineering structures. The finite element method offers a variety of sophisticated element …

We study an old mathematical model, developed before the computer era, for analyzing the strength of a stiffened shell roof. The specific problem considered is a textbook example …
We analyse the performance of direct solvers when applied to a system of linear equations arising from an h-adapted, C 0 finite element space. Theoretical estimates are derived for …
In January 2008, the International Association of Computational Mechanics (IACM) invited the scientific community to solve the Girkmann problem by finite element methods. The …

In this paper, we consider three-dimensional grids with tetrahedral finite elements, and the graph grammar model for mesh generation and adaptation as well as for the simultaneous …
We consider two graph grammar based Petri nets models for anisotropic refinements of three dimensional hexahedral grids. The first one detects possible dead-end problems …

We analyse a finite-element discretisation of a differential equation describing an axisymmetrically loaded thin shell. The problem is singularly perturbed when the thickness …
