With the massive consumption of oil and the serious environmental problems, all countries are looking for clean and efficient energy to solve the current energy shortage and environmental pollution. Automobile is not only a big consumer of oil, but also one of the main sources of air pollution. In the process of searching for alternative fuels, the liquefied natural gas (LNG) vehicle has become the development trend of new energy automobile in the world [1]. However, due to the cryogenic nature and flammable characteristic of LNG, the accidents of LNG vehicle often occur, and the consequences can be catastrophic [2,3]. The accidental leakage of LNG may cause low-temperature damage on material or human body. When LNG leaks into air, it may produce a chemical explosion or fire. Under some conditions, the direct contact of LNG and water can produce a rapid phase transition (RPT) explosion, which could cause damage to adjacent materials or structures, leading to more serious consequences [4,5]. Regrettably, the safety regulations and standards for LNG vehicle are relatively backward; the common breakdown and emergency method need more attention.Rapid phase transition (RPT) is a complex process, which has the thermodynamic and hydrodynamic properties.

“…The stress-strain curves obtained for AISI 321 herein agrees well with ref. 48 Using the above input parameters, various stages of the true stress-strain curve was fit to the expressions in equation (2). The data fitting showed that a 6-stage material model was fitting satisfactorily to the stressstrain data of AISI 321 prior to necking.…”

“…Non-linear elasto-plastic behavior of structures can be analyzed using general purpose finite element (FE) codes by providing the non-linear stress-strain data for a material. [1][2][3][4] Uniaxial non-linear stress-strain behavior of a ductile material is commonly expressed through analytical material models, for instance the Ramberg-Osgood (R-O) model. 5 The experimental stress-strain data is fit to such a model for determining the unknown material parameters.…”

Ramberg-Osgood (R-O) type stress-strain models are commonly employed during elasto-plastic analysis of metals. Recently, 2-stage and 3-stage R-O variant models have been proposed to replicate stress-strain behavior under large plastic deformation. The complexity of these models increases with the addition of each stage. Moreover, these models have considered deformation till necking only. In this paper, a simplistic multi-stage constitutive model is proposed to capture the strain-hardening non-linearity shown by metals including its post necking behavior. The constitutive parameters of the proposed stress-strain model can be determined using only elastic modulus and yield strength. 3-D digital image correlation was used as an experimental tool for measuring full-field strains on the specimens, which were subsequently utilized to obtain the material parameters. Our constitutive model is demonstrated with an aerospace-grade stainless steel AISI 321 wherein deformation response averaged over the gauge length (GL) and at a local necking zone are compared. The resulting averaged and local material parameters obtained from the proposed model provide interesting insights into the pre and post necking deformation behavior. Our constitutive model would be useful for characterizing highly ductile metals which may or may not depict non-linear strain hardening behavior including their post necking deformations.

“…Faupel (1956) firstly proposed a classic burst pressure prediction formula through a large amount of experimental data. Wellinger and Uebing (Brabin et al ., 2011) also established an empirical formula that was considered sufficiently accurate. Zhu and Leis (Zhu, 2023) presented the general burst pressure solutions for thin and thick-walled cylinders in terms of the average shear stress yield criterion.…”

PurposeThe high-pressure accumulator has been widely used in the hydraulic system. Failure pressure prediction is crucial for the safe design and integrity assessment of the accumulators. The purpose of this study is to accurately predict the burst pressure and location for the accumulator shells due to internal pressure.Design/methodology/approachThis study concentrates the non-linear finite element simulation procedure, which allows determination of the burst pressure and crack location using extensive plastic straining criterion. Meanwhile, the full-scale hydraulic burst test and the analytical solution are conducted for comparative analysis.FindingsA good agreement between predicted and measured the burst pressure that was obtained, and the predicted failure point coincided very well with the fracture location of the actual shell very well. Meanwhile, the burst pressure of the shells increases with wall thickness, independent of the length. It can be said that the non-linear finite element method can be employed to predict the failure behavior of a cylindrical shell with sufficient accuracy.Originality/valueThis paper can provide a designer with additional insight into how the pressurized hollow cylinder might fail, and the failure pressure has been predicted accurately with a minimum error below 1%, comparing the numerical results with experimental data.
