Polymers in the construction of serviceless sliding bearings
Archives of Civil and Mechanical Engineering - Tập 7 - Trang 139-150 - 2007
The application range of polymers and their composites in service-less sliding bearings, i.e. bearings that do not require lubrication supervision and maintenance, was defined. A survey of polymers having good sliding properties was done. A general characteristic and classification of polymer composites was presented. The structure and properties of the following composites were discussed: anti-fr......

Study of the isothermal bainitic transformation and austenite stability in an advanced Al-rich medium-Mn steel
Archives of Civil and Mechanical Engineering - Tập 22 - Trang 1-14 - 2022
Isothermal bainitic transformation of a lean medium-Mn steel containing (in mass%) 0.18C–3.6Mn–1.7Al–0.23Si–0.2Mo–0.04–Nb after full austenitization at 1100 ºC was studied by means of high resolution dilatometry. The effects of isothermal holding temperatures ranging from 450 to 350 °C on the bainitic transformation kinetics was studied experimentally characterizing the microstructure present afte......

Advanced high strength steels for automotive industry
Archives of Civil and Mechanical Engineering - Tập 8 - Trang 103-117 - 2008
The aim of this paper is to present the basic concepts of advanced high strength steels (AHSS) for use in the automobile industry, including chemical composition design, microstructure and mechanical properties development during thermomechanical processing, production technology characterisation, potential applications and performance in service. AHSS steels are considered to be the major materia......
Soft computing approaches for comparative prediction of ram tensile and shear strength in aluminium–stainless steel explosive cladding
Archives of Civil and Mechanical Engineering - Tập 22 - Trang 1-16 - 2022
This study deals with the application of soft computing techniques viz., response surface methodology, artificial neural network, radial basis function network and support vector regression in analyzing and predicting the ram tensile and shear strengths of aluminium 5052–stainless steel 316 explosive clads, having different interlayer. 60 explosive cladding experiments were conducted, based on cen......
Application of the difference equation method to the vibrations analysis of infinite Rayleigh beams by the isogeometric approach
Archives of Civil and Mechanical Engineering - Tập 15 - Trang 1108-1117 - 2015
An efficient method of vibration investigations of infinite Rayleigh beams applied to the isogeometric analysis called NURBS (non-uniform rational B-splines) is proposed. The research objective is to examine the influence of rotational inertia effects on the dynamic behaviour of the discrete systems approximated by NURBS and compare obtained results with the finite element method (FEM) and exact o......

A parametric analysis of free vibration and bending behavior of sandwich beam containing an open-cell metal foam core
Archives of Civil and Mechanical Engineering - Tập 22 - Trang 1-15 - 2022
Free vibration and bending behavior of sandwich beams containing open-cell metal foam core are studied in the present work using zigzag theory. Hamilton’s principle and the principle of minimum potential energy are applied for determining the governing equations for free vibration and bending behavior, respectively. Three types of distribution of pores are used during the present study. The influe......
Effect of dual beam laser welding on microstructure-property relationships of hot-rolled complex phase steel sheets
Archives of Civil and Mechanical Engineering - Tập 17 - Trang 145-153 - 2016
The work addresses microstructure-property relationships of hot-rolled complex phase steel sheets subjected to various conditions of dual beam laser welding. The article also contains a comparison between single-spot and twin-spot laser welding. Test-related joints were made using a Yb:YAG disc laser having a maximum power of 12 kW and a welding head enabling the focusing of a laser beam on two sp......
