 Abstract
This article presents a study on the state of stress and strain in tube-to-tubular plate joint. The analysis using Finite Element Method (FEM), for two types of expander surfaces: one in which the surface is smooth hole tubular plate (ledge), other, in which, hole surface practiced a groove.

 Rezumat
In acest articol este prezentat un studiu privind starea de tensiuni şi deformaţii în îmbinările prin mandrinare. Analiza s-a efectuat folosind Metoda Elementelor Finite (MEF), pentru dou¬ă tipuri de suprafeţe de mandrinare: una, la care suprafaţa orificiului plăcii tubulare este lisă, cealaltă, la care, pe suprafaţa orificiului este practicată o canelură.
