Proc. ASME. PVP2020, Volume 3: Design and Analysis, V003T03A004, August 3, 2020
Paper No: PVP2020-21183
..., this paper focuses on the research of the transient sloshing of the internal liquid in the shipboard pressure vessel. In this paper, during analyzing the liquid sloshing dynamic of the shipboard pressure vessel, an obvious cycle is got. Considering the operation condition of lateral inclination, longitudinal...

Paper No: PVP2020-21545
... of metal components is to apply an environmental fatigue penalty factor (F en ) to the partial usage factor obtained from the design fatigue curve for each stress cycle. Fatigue evaluations have historically been performed by assuming that temperature transient loads occur at conservatively high rates...

Proc. ASME. PVP2013, Volume 3: Design and Analysis, V003T03A109, July 14–18, 2013
Paper No: PVP2013-97596
... The effects of severe thermal- and pressure-transients on coated substrates with indentation-induced, blister defects were analyzed using experimental and finite-element methods. An explicit FEA approach was first used to assess the transient thermal- and stress-states and the propensity...

Paper No: PVP2011-57604
... The effects of severe thermal-transients on coated substrates with indentation-induced, blister type defects were analyzed using finite-element methods. Both explicit and implicit approaches were used depending on the timeframe under scrutiny. For the modeling, an axisymmetric mesh and cohesive...

Paper No: PVP2007-26602
..., thermal behavior of the pipe flange joints is discussed under steady state loading with and without internal pressure and under transient loading condition without internal pressure. The present design codes also do not address the effects of steady state and thermal transient loading on the structural...

Proc. ASME. PVP2008, Volume 3: Design and Analysis, 657-664, July 27–31, 2008
Paper No: PVP2008-61824
.... For the two geometries explored (thick-walled cylinder under an internal transient with external convection and a slab with one adiabatic surface), excellent agreement was seen with various test cases for histories based on either temperature or strain. However, the strain-based solutions may be preferable...
