With an emphasis on real-world problems, this book reviews the basics of optimization of
frame structures such as trusses, building frames, and long-span trusses. It introduces …

In this paper we show how to significantly improve the robustness and the efficiency of the
Newton method in geometrically non-linear structural problems discretized via displacement …

A new geometrically nonlinear model for homogeneous and isotropic beams with generic
section including non-uniform war** due to torsion and shear is derived. Each section is …

Packing problems, which ask how to arrange a collection of objects in space to meet certain
criteria, are important in a great many physical and biological systems, where geometrical …

What we call the implicit corotational method is proposed as a tool to obtain geometrically
exact nonlinear models for structural elements, such as beams or shells, undergoing finite …

The identification of finite mechanisms in statically and kinematically indeterminate
structures is, in general, a difficult problem. However, Kangwai and Guest [1999] showed …

Control over the deformation behaviour that a cellular structure shows in response to
imposed external forces is a requirement for the effective design of mechanical …

The analysis of slender structures, characterized by complex buckling and postbuckling
phenomena and by a strong imperfection sensitivity, is heavily penalized by the lack of …

A general method for evaluating the order of infinitesimal mechanism is presented for 3-
dimensional bar-joint mechanism, which is defined as assembly of rigid bars connected to …

The traditional methods taking nodal displacements as primary unknown variables are only
applicable to the determination of the static and kinematic determinacy of pin-bar …
