..., or induce transient cavitation, a particular concern for hydrocarbon liquids. This paper will use examples of computer modeling to reveal how common system events such as pump trips or valve closures induce low pressure transient waves that have potential to be just as destructive as more intuitive high...

...Abstract Abstract Transient surge modeling remains to be a specialized task and therefore quite unfamiliar to many engineers and designers. The process for discerning when to conduct a model can be vague. The process for how to conduct a model can be even more unclear and quite daunting...

... were not initially known, a simple laminate model of the tube was done using carbon-epoxy data. This resulted in an over prediction of the failure load. The exact material used was tested and a new laminate model was created that better matched the experimental results. The results from the experiment...

...Abstract Abstract We present VistaDam , a physics-based ductile fracture material model that is tailored to predict failure in thin metal sheets. VistaDam is based on a three invariant plasticity model in which metal fracture is dependent on the combined evolution of the triaxial stresses...
