RISViscoelastic and Damage Model of Polyethylene Pipe Material for Slow Crack Growth Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Polyethylene (PE) pipe is widely used for oil and gas transportation. Slow crack growth (SCG) is the main failure mechanism of PE pipes. Current SCG resistance testing methods for PE pipes have significant drawbacks, ...
Multi-Physics Investigations on the Gas-Powder Flow and the Molten Pool Dynamics During Directed Energy Deposition Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to establish a high-fidelity mechanism model for investigating the molten pool behaviors during directed energy deposition (DED) process, a molten pool dynamics model combined with the discrete element method is ...
Finite Element Analysis of Buried Polyethylene Pipe Subjected to Seismic Landslide
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Polyethylene (PE) pipes are widely used in natural gas transportation systems in urban areas nowadays. As landslide caused by earthquake would cause destructive damage to buried pipes, increasing attention is attracted to ...
