Analiza Drgań Samowzbudnych Wirnika o Dwóch Stopniach Swobody
Engineering Transactions, 1973 In the paper stationary, self-excited vibrations of rotor with two degrees of freedom, excited by the action of internal friction within the material of the rotor are analyzed. The characteristics of elasticity and internal friction are assumed to be non-

Advanced Engineering Materials, EarlyView.CT‐based finite element simulations combined with in situ X‐ray computed tomography are used to analyze insert pull‐out in nickel‐coated polymer foams. Despite variations in material parameters, deformation consistently concentrates within a narrow annular region around the insert.

Advanced Engineering Materials, EarlyView.This study examines Invar composites reinforced with titanium carbide (TiC) and titanium nitride (TiN) using laser powder bed fusion (LPBF). It presents the influence of reinforcements on microstructure, tensile properties, and thermal expansion. Results show that TiC effectively strengthens Invar while maintaining low thermal expansion, whereas TiN ...

Le Journal de Physique Colloques, 1971 Preliminary results of internal friction measurements in rhenium between 100 and 350 °K are reported. For a frequency of about 300 Hz, an internal friction peak is observed in cold-rolled specimens at about 275 °K, together with a shoulder near 230 °K. Assuming that this peak is due to dislocation relaxation, an activation enthalpy of approximately 0.6

Advanced Engineering Materials, EarlyView.Near‐surface deuterium enrichment profiles for different microstructural types of TiAl after exposure at 700 °C in a heavy water‐containing environment. The deuterium levels are significantly higher than expected from natural occurrence, indicating that the heavy water dissociated during the exposure treatment and entered the specimens.

Advanced Engineering Materials, EarlyView.To enhance through‐thickness conductivity without sacrificing impregnation, large spherical graphite particles are intentionally employed in a low‐viscosity resin. Unlike finer conductive fillers, these particles remain outside the fiber bundles and accumulate in resin‐rich interlaminar regions during molding.

Change of internal friction on aluminium
Production Engineering Archives, 2015 The article is focused on the analysis of changes in the dependence on temperature on the aluminium alloy EN AC 51200 (10,1% Mg, 1,32% Si and 0,43% Mn) by internal friction.
