Sustainable development of pressure equipment using 3D Digital Image Correlation method

Abstract

As pressure equipment is most commonly used in various industrial fields, making manufacturing processes eco-friendlier (e.g. mass reduction of the final product, material and energy savings etc.) and transition to sustainable production by developing eco-innovative products will have positive influence on the environment. The aim of this paper is to analyse globe valve housing exposed to internal pressure using full-field experimental 3D Digital Image Correlation (3D-DIC) method and numerical strain and stress data in order to propose improvements for more sustainable development, with respect to practical engineering application of EN standards. The highest von Mises strain values around 0.03 % were measured on the point of highest geometrical discontinuity, sphere/cylinder intersection. Stresses of the examined globe valve using numerical and theoretical approach are significantly below material yield limit and allowable stress for internal pressure values of 30 bar, that is significantly higher than nominal operating pressure of 6 bar, proving that structure is over dimensioned and can be optimized. New experimental procedure development and application in full-field strain analysis contributes to increased valve housing reliability, mass reduction and material and energy savings during manufacturing which directly affects its eco-friendliness, lowers manufacturing price and increases market competitiveness. Keywords 3D Digital Image Correlation method; Environmental protection; globe valve housing; internal pressure; sustainable development. Highlights • Analytical, numerical and experimental investigation of globe valve is performed. • 3D experimental strain field on sphere/cylinder intersection is measured. • Analysis showed that valve housing is over dimensioned. • Eco-friendliness in globe valve production can be achieved.

Experimental Evaluation of Hoop Stress–Strain State of 3D-Printed Pipe Ring Tensile Specimens

“…Calibration was conducted as part of the preexperimental preparations. Several studies [21][22][23][24][25][26][27] discuss the detailed mode of operation, calibration, preparation of the measuring object, and measuring technique. The Aramis setup parameters for this study were as follows:…”

“…DIC is an optical, non-contact method that can provide the full 3D strain/displacement field [15,16]. DIC is independent of the material tested, as well as of the shape of the object, which enables its application in various fields, such as structural integrity, biomaterials, and polymers [17][18][19][20][21][22][23][24][25][26][27]. It is important to note that in all the studies mentioned before, one camera was used for the displacement and strain analysis.…”

“…Calibration was completed as part of the testing setup. A few studies [25][26][27][28][29][30][31][32] go into great detail about the mode of calibration, object preparation, operation and measuring procedure. 3D scanner measurements: Following a satisfactory calibration, a measurement was made.…”
