Auxetic materials and structures are a novel class of materials which have negative Poisson's ratio. They have improved mechanical properties such as fracture toughness, indentation resistance, etc. They have several potential applications in medical, sports, automobile, defense, etc. Design and modeling of auxetic materials is still in progress. In this article we briefly introduce these materials and their different features and properties.

The article presents an analysis of the macrostructure and mechanical properties of spot welds of joints made by Refill Friction Spot Stir Welding (RFSSW) method. RFSSW is a relatively new technology that is gaining wider use, not only in the automotive and aviation industries because it is a less energy intensive method than resistance spot welding. The primary focus of the article is the effect of welding time on the quality of the welded joints of sheet metal using the aforementioned method. The research was conducted on a joint between two pieces of sheet metal of various thicknesses (1.6 mm and 0.8 mm) made of a common aviation grade aluminium alloy 7075-T6 Alclad. Metallographic sections of select variants were made in order to analyze the structure of the joint. Strength tests with a static load were conducted in different loading configurations. A traditional tensile strength test was conducted on the lap joint, which revealed a complex stress state within the joint and an analogous test was conducted with the use of a stiffening holder that ensured a pure shear state in the joint. Peel tests were also performed on the lap joints with using a special holder.

“…Another benefit would be the ability of joining materials with different properties and better safety conditions in the workplace, when compared to traditional welding methods [4,8,9,10]. This technique can be used to joint different types of materials like composites [11,12], thermoplastics [13,14] and non-weld-able alloys [4,5].…”

Abstract. The paper presents the results of an analysis of the effect of welding parameters on the load capacity of joints obtained by the refill friction stir spot welding (RFSSW) method. This technology has a prospective application in aerospace and automotive industries, especially for aluminium alloys. The research was conducted for the overlapping joints made of two 7075-T6 aluminium alloy sheets with thicknesses 1.6 mm and 0.8 mm. Strength tests were conducted for two variants of loading the joint. The experiments were conducted according to statistical Hartley's plan PS/DS-P:Ha3. The welding times t was varied in the range of 1.5 ÷ 3.5 s, the tool plunge depth g in the range of 1.5 ÷ 1.9 mm, and the tool rotational speed n in the range of 2000 ÷ 2800 rpm. For these parameters the analysis of experiment reproducibility, impact significance and adequacy of equations were made. The results of analysis according to the design of the experiment (DOE) indicate that all analyzed parameters have significant influence on the load capacity of joints. The biggest load capacity of joints in the case of the first variant was gained at the maximum spindle speed of 2800 rpm, the minimum tool plunge depth of 1.5 mm and welding time of 1.5 s. For the second variant, the maximum load capacity of joints was gained at the spindle speed of 2400 rpm, tool plunge depth of 1.5 mm and welding time of 2.5 s.
