| dc.description.abstract | The eigenstress (residual stress) state of a thin superficial layer of an electrodeposit is considered. The analysis is based on Ilyushin´s theory of plasticity. It is established that the state of stress in the superficial layer is equal biaxial compression or tension defined for the elastic state according to formula (9), for initial stress, where E, µ and β are the modulus of elasticity, Poisson´s ratio and initial strain for the coating, respectively. At β>0 there occurs biaxial compression, at β<0 there occurs biaxial tension. It is shown that eigenstresses (residual stresses) in the thick deposit are expressed as the sum of initial stress and additional stress. | eng |
| dc.description.abstract | Näidatakse, et omapingete tekkimise põhjuseks galvaanilistes katetes on mittevaba omadeformatsioon. Omapingete määramiseks kasutatakse väikeste elastilis-plastiliste deformatsioonide teooria põhivõrrandeid ja üldistatud Neumanni hüpoteesi. Selgub, et õhukestes galvaanilistes katetes tekib kaheteljeline võrdsete peapingetega pingeolek. | est |
| dc.description.abstract | In der Arbeit wird gezeigt, daß die Entstehung der Eigenspannungen in den galvanischen Überzügen durch die nichtfreie Eiegendeformation verursacht wird. Zur Bestimmung der Eigenspannungen werden die Grundgleichungen der Theorie der kleinen elastisch-plastischen Deformationen und die verallgemeinerte Neumann-Hypothese verwendent. Es ergibt sich, daß in den dünnen galvanischen Überzügen ein zweiachsiger Spannungszustand mit gleichen Hauptspannungen entsteht. | ger |
