TLDR
The International Institute of Welding (IIW) and many other sponsors helped organizers to collect these valuable studies, which provide an important reference for civil and mechanical engineers, architects, design-ers and fabricators, as well as managers in a rangeof industries including building, transport, materialshandling, shipbuilding, aircraft, chemical and offshoreengineering.
Abstract
structural optimization, fatigue design, frames, platedstructures, residual welding stresses and distortions,static stresses in welded connections, hollow sections,welding technology, applications, applied mechanics.Authors are experts from 20 countries, ensuring awide spectrum and importance of the themes covered.The International Institute of Welding (IIW) andmany other sponsors helped organizers to collect thesevaluable studies, which provide an important referencefor civil and mechanical engineers, architects, design-ers and fabricators, as well as managers in a rangeof industries including building, transport, materialshandling, shipbuilding, aircraft, chemical and offshoreengineering.Most of the work relate to structural optimization,in which the structural safety and fitness for productionare guaranteed by fulfilling the design and fabricationconstraints and the economy is achieved by minimiza-tion of a cost function. Welding technology and stressesarising from welded connections represent a significantpart of the remaining papers. The book includes studieson structural analysis and design concerning fracture,instability, large deformations, fatigue, earthquake andfire loading.Papers can help the work of engineers, designers,producers, managers and researchers in designing andproducing competitive welded structures.

An analytical method to estimate the total installed cost of structural steel building frames during early design

TL;DR: In this paper, the material, fabrication, and erection cost of steel frames based on early-design information is estimated using the Integrated Steel Design (ISD) method. But the method is not suitable for large-scale projects.

A beam model for large displacement analysis of flexibly connected thin-walled beam-type structures

TL;DR: In this paper, a beam formulation for large displacement analysis of beam-type structures with flexible connections is presented, which is based on updated Lagrangian incremental formulation and the nonlinear displacement field of thin-walled cross-sections, which accounts for restrained warping and the second-order displacement terms due to large rotations.

Crash energy absorption of multi-segments crash box under frontal load

TL;DR: In this article, a finite element analysis on a cylindrical crash box with multi-segments design is performed and the deformation behavior and crash energy absorption are observed, and the number of crash box segments used in this investigation are two segments, three segments with a sequence diameter and three segment with alternating diameter.

Correlation between microstructural features and tensile strength for friction welded joints of AA-7005 aluminum alloy

TL;DR: The role of micro-structural features on tensile strength of resultant joints is discussed in this paper, where the authors show the formation of intermetallic phases during the welding process which cannot be extruded from the interface.

Friction welding of dissimilar pure metals

TL;DR: In this paper, the influence of interaction time in continuous drive friction welding on microstructure and tensile properties is studied and it is shown that increased interaction time led to decrease in strength in eutectoid forming and insoluble systems and improved strength in soluble systems.

Effect of friction welding parameters on mechanical and metallurgical properties of ferritic stainless steel

TL;DR: In this article, a continuous drive friction welding machine was used to join cylindrical specimens of ferritic stainless steel of similar composition and shape (equal diameter and length) in order to understand the role of parameters on the strength related aspects of friction processed joints.

Effect of rotational speed on the interface properties of friction-welded AISI 304L to 4340 steel

TL;DR: In this paper, the authors investigated the interface properties in terms of rotational speed in friction-welded AISI 304L to alloy steel and found that the thickness of full plastic deformed zone (FPDZ) formed at interface reduce as a result of more mass discarded from the welding interface with increase of the rotational speeds.
