... a novel approach for modelling sealability/leakage in metal-to-metal surfaces. It utilizes a contact-mechanics and a fluid-flow model. Deterministic multi-asperity contact-mechanics model provides quantitative estimation of gasket contact stresses, contact gap, and contact area. The leakage model uses...

... is not pressure-dependent and, (2) fracture stiffness (or compliance) is assumed to be constant during fracture closure. Fracture closure is a gradual process that starts when asperities at the fracture tip first come into contact with each other. As pressure declines due to leak-off, more and more...

..., stress release associated with overall rupture and sub-events which is suggestive of decreasing frictional resistance due to the presence of fluids. Magnitudes for sub-events increase suggesting increasing rupture surface akin to increased slip over a larger contact area such as an asperity. Rupture...

... fracture cross-sections. Therefore, the narrowest points, which are the highest asperities, come into contact first and act as pillars to support the fracture ( Fig. 3 ). The subtraction, ( w i -w min ), leads to the new width profile for the next calculation step. By following the same procedure, we...
