AB  - The purpose of this work is to present analytical and numerical determination of equivalent stress and deformation of open section thin-walled U and Z cantilever beams loaded with torsion. This work can be divided into two parts. In the first part of this paper, equivalent stress and deformation are obtained by analytical calculation for encastered model over the whole cross section. In the second part, the finite element method is applied for four different encastered models and the obtained results are compared with the analytical calculation.

AB  - The subject of the paper is the temperature distribution in the thin metallic ferromagnetic plate influenced by moving linear high frequency induction heater. As a result of high frequency electromagnetic field, conducting currents appear in the part of the plate. Distribution of the eddy-current power across the plate thickness is obtained by use of complex analysis. The influences of the heater frequency, magnetic field intensity and plate thickness on the heat power density were discussed. By treating this power as a moving heat source, differential equations governing distribution of the temperature field are formulated. Temperature across the plate thickness is assumed to be in linear form. Differential equations are analytically solved by using integral-transform technique, Fourier finite-sine and finite-cosine transform and Laplace transform. The influence of the heater velocity to the plate temperature is presented on numerical examples based on theoretically obtained results.

AB  - Experimental and Numerical Analysis of Local Mechanical Properties of Globe Valve Housing One of the most widely used industrial valves is globe valve. Due to wide industrial application, the valve is subjected to various types of loads - static, dynamic, thermal etc. which causes valve housing failures. Based on previous experiences and research, valve housing failure is expected in the areas of high stress concentration, such as high geometrical discontinuity. This paper is focused to investigate the possibility to analyze local strain fields of geometrically complex globe valve housing subjected to internal pressure using non-contact 3D optical deformation analysis in order to verify numerical model. Experimental system consists of cameras for 3D displacement and strain analysis and software Aramis. Using the Finite Element Method (FEM), numerical model subjected to different loads was analyzed. It is found that the predictions from the model agree well with experimental results as the result differences between two methods in the area of the highest strain values vary 30 % and in the spherical and cylindrical parts result variation is 14.8 %. Experimental and numerical results demonstrate that the experimental method is adequate for solving geometrically complex problems and determining local mechanical properties.

AB  - The leakage of tube-tubesheet joint of feedwater heater on the inlet required redesign and repair by additional tube welding. The original design took into account only the sealing, and subsequently after some period leakage occurred due to tube displacement in tubesheet, caused by thermal and mechanical overload. Repair procedure included cutting out the heater header along the welded joint, preparing and welding the tubes to the tubesheet and repeated welding of the header. The header and tubesheet are made of carbon steel. Welding procedure anticipated an austenitic soft interlayer and local heat treatment for residual stress relaxation before final joining. Fitness-for-purpose assessment has been issued and models were developed by finite element analysis according to the design solution and condition after repair. The results of mechanical and thermal responses of model confirmed that repaired feedwater heater is fit for purpose.
AB  - Pricurivanje na spoju cevi i cevne place na ulazu u zagrejač vode je zahtevalo rekonstrukciju i popravku dodatnim zavarivanjem cevi. Prvobitnim projektom je u obzir uzeto samo zaptivanje i posle nekog vremena u radu je došlo do curenja zbog pomeranja cevi u cevnoj ploči, izazvanog termičkim i mehaničkim preopterećenjem. Postupak popravke je predvideo isecanje glave zagrejača po zavarenom spoju, pripremu i zavarivanje cevi za cevnu ploču, i ponovno zavarivanje glave. Glava i cevna ploča su izrađeni od ugljeničnog čelika. Postupak zavarivanja je predvideo austenitni meki sloj i lokalnu termičku obradu za otpuštanje zaostalih napona pre završnog spajanja. Ocena podobnosti za upotrebu je zahtevana i razvijeni su modeli prema projektnom rešenju i stanju posle popravke analizom konačnim elementima Rezultati mehaničkog i termičkog odgovora modela su potvrdili da je popravljeni zagrejač napojne vode podoban za upotrebu.
