Opis:
In the paper a fragment of research on development of modelling methods of asymmetrical multi-bolted flange connections is presented. The effect of the bolt modelling method in a single bolted joint on both the stiffness characteristics of elements joined in the multi-bolted flange connection and bold forces have been examined. An analysis of the multi-bolted flange connection is carried out for selected models created using the finite element method (FEM). Guidelines for the selection of the bolt modelling method in the case of both the stiffness analysis and the load analysis of multi-bolted flange connections have been pointed out.

Opis:
The paper presents the results of an analysis of the geometrical structure of Fe-Al intermetallic protective coatings sprayed under specified gun detonation spraying (GDS) conditions. Two barrel lengths, two powder injection positions (PIP) at the moment of spark detonation, and two numbers of GDS shots with 6.66 Hz frequency were applied as variable parameters in the GDS process. Surface profile measurements were conducted by contact profilometry with the use of the TOPO-01 system and the Mitutoyo SJ 210 profilometer. The measured parameters were used to analyze surface topography in two-dimensional (2D) and three-dimensional (3D) systems. It was assumed that roughness can be regarded as a non-stationary parameter of variance in surface amplitude which is highly dependent on the sampling rate and spraying distance. Therefore, changes in surface amplitude parameters and functional properties were analyzed across segments with a length (ln) of 1.25, 4 and 12.5 mm. The development of the geometric structure of the surface was analyzed with the RMS (Root Mean Square) fractal method, and the geometric structure of the surface stretched by several orders of magnitude was evaluated based on the correlation between roughness (Rq), segment length (ln) and fractal dimension (D). The RMS method and the calculated fractal dimension (D) supported the characterization of the geometric structure of intermetallic Fe-Al protective coatings subjected to GDS under the specified process conditions based on the roughness profiles of surface segments with a different length (ln).

Opis:
In this study, aluminum bronze BA1032 was analyzed thermally by differential scanning calorimetry (DSC). The article presents the results of measurements of phase transitions occurring in aluminum bronze at a temperature of up to 600°C. Thermal analyses were conducted at constant heating rates of 5°C/min, 10°C/min and 15°C/min.
