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.
