Special Issue Information

Dear Colleagues,

Clarifying the mechanical behavior of alloys is quite important to evaluate their performance, such as strength, ductility, toughness, workability, formability, etc. Actually, alloys undergo, not only simple loading, such as tension, compression, and torsion, but also quite complicated loading conditions via combinations of simple loading with proportional and non-proportional histories. Additionally, products with high performance at high-speed deformation, such as high-energy absorption, including a fracture characteristic, are quite useful to avoid the fatal accidents of transportation equipment. In both cases, strain rate sensitivity in the inelastic deformation of alloys holds the key, and it is important to clarify dynamic or impact effects of the phenomena, related to the rate sensitivity of the materials. In the Special Issue, a broad range of research works related to deformation behavior of alloys are invited, as well as interdisciplinary works concerning these topics. In addition, fundamental research works on testing methods and computational simulations are included.

This Special Issue will be composed of articles reporting on new and progressive research results, as well as reviews of particular classes of fundamental deformation behaviors of alloys and their applications. Manuscripts will be welcomed from both fundamental scientific researchers and authors belonging to industrial companies involved in the field.

Title: The Quasi-Static Compressive Behaviour of in situ Foam-Filled Structures
Authors: Emanoil Linul, Liviu Marsavina and Jaroslav Kováčik
Affiliation: Politehnica University of Timisoara and Slovak Academy of Sciences
Abstract: Cellular materials such as polymeric and metallic foams are a relatively new class of structural and functional materials exhibiting unique mechanical and physical properties that make them attractive in a many wide range of applications in structural engineering, especially as core material in lightweight constructions. The aim of this paper is to investigate the quasi-static compressive axial crush performance of in-situ light aluminium alloy foam-filled tubes (FFTs) prepared by powder metallurgy processing route. By this method, the circular thin-walled empty steel tube (ET) is filled with an aluminium alloy foam (AF) during its formation. Axial compressive behaviour of the individual components (AFs and ETs) and FFTs was studied and evaluated using uniaxial compression tests, exploring their deformation and failure mechanisms. The FFTs deform by axisymmetric crushing mode with the formation of two visible concertina folds. Because of the interaction effect between the AFs as filler material and the ETs, both the experimental results (such as crushing strength and absorbed energy) and SEM images confirm a more stable and improved crush performance of the in-situ FFTs under axial compressive loads.
