Abstract
Process engineering encompasses diverse industrial fields, such as chemical, petrochemical, pharmaceutical, biotechnological etc., and pressure equipment is an indispensable part of every industrial plants. Due to wide range of applications, pressure equipment comes in different shapes, from simple to very complex, and can be subjected to different loadings in its working life (static, dynamic, thermal etc.) so the knowledge of mechanical behaviour is of great importance. This paper presents several examples of application of 3D Digital Image Correlation method (3D-DIC)for simple shaped objects, as well as for geometrically complex structures. A 3D Digital Image Correlation method is an optical method that overcomes the limitations of conventional methods and enables full-field displacement and strain measurement. Aramis system was used for the experimental analysis. Welded joint standardized specimen is used as an example for simple shaped object. For geometrically complex structure, several examples are used: globe valve housing with distinctive sphere/cylinder intersection, cylindrical horizontal pressure vessel with cylindrical nozzles and T joint pipe. Experimental results demonstrate that the 3D-DIC method is adequate for solving geometrically complex problems and provides an opportunity for further development and improvement for practical industrial application
