SMAT2008M27THE ESTIMATION OF THE RESIDUAL STRESS LEVEL FROM THEWELDED COMPONENTSCONF. DR. ING. VĂDUVOIU GH.- UNIV. CRAIOVA, FAC. MECANICĂPROF. DR. ING. TĂRÂŢĂ DANIELA - UNIV. CRAIOVA, FAC. MECANICĂAbstract : The goal of this paper is to present the results of the researches concerning the development of a controlmethod dedicated to estimate the residual stress level in the welded railway recipients. The studies were focused on theparticular situation when a mechanical stress relaxation treatment was applied after the welding processKey words: residual stress, stress relief, heat treatment, vibration methodSMAT2008M28CONSIDERATIONS LOOKING THE CALCULUS OF MULTILAYERCOMPOSITE FRAMES TO THERMAL SOLICITATIONSGabriela Monica PANĂAbstract: The paper puts in evidence the particular problems set by the calculus of the compositeframes through the method of the finite elements to thermal solicitations. Using of the multilayer modelcan represent the repartition of the temperature in each layer through linear approximations, convenientlysimplifying the problem. This method permits, for anisotropic material, to take count of the componentmaterials properties depending on temperature.
