dc.descriptionThe research focuses on assessing the burst strength of the 14.2 Kg LPG cylinders for which the model is prepared according to Nepal and Indian Standards. 2.61 mm is chosen as the thickness of the LPG cylinder for which the minimum internal pressure is calculated using the ASME BPVC Section VIII, Division 1 and Nepal Standard Code using the yield strength as the allowable stress limit.
dc.description.abstractThe research focuses on assessing the burst strength of the 14.2 Kg LPG cylinders for which the model is prepared according to Nepal and Indian Standards. 2.61 mm is chosen as the thickness of the LPG cylinder for which the minimum internal pressure is calculated using the ASME BPVC Section VIII, Division 1 and Nepal Standard Code using the yield strength as the allowable stress limit. The yield and ultimate tensile strength are obtained from the uniaxial tensile tests, while burst pressure is obtained from the hydrostatic pressure burst test. The test conducted on 9 different LPG cylinder samples resulted in an average yield strength, ultimate tensile strength and burst pressure of 283.879, 421.045 and 8.72 MPa respectively. The analytical burst pressure as per shell theory obtained is 6.98 MPa. Numerical simulation as per ASME BPVC Section VIII, Division 2, Part 5 yields burst pressure of 7.0014, 7.506713, and 8.421 MPa from Elastic, Limit Load and Elastic Plastic analysis respectively with, elastic plastic analysis considered most realistic approach. Since LPG cylinders are symmetrical about the longitudinal axis, axisymmetric 2D analysis is performed.
