Sentences with phrase «by friction stresses»

Roth asks, «Do the vents extend down to a subsurface ocean or are the ejecta simply from warmed ice caused by friction stresses near the surface?»

Not exact matches

Highly destructive earthquakes caused by subduction occur because of excessive friction that develops during the sliding process, resulting in a build - up of stress.

Coulomb's equation states that in order to slide one hand against the other the shear stress — akin to the force applied to slide your hands — divided by the surrounding pressure — squeezing the sand together — must equal something called the friction coefficient.

But, the friction model requires materials to expand — or dilate — once stress surpasses a threshold and particles lock into place so that they are unable to squeeze by each other, as in the hydrodynamic model.

Following a frictional failure in the labquake, the shearing block moves or displaces, while the gouge material simultaneously dilates and strengthens, as shown by measurably increasing shear stress and friction.

Here's the insidious problem with so many of these fad diets: Though they enthusiastically promise relief via not having to «obsess over calories,» they ironically induce more stress by imposing excessive food restrictions that cause friction with normal life.

Because myofascia is relatively superficial, it can be influenced through foam rolling (self - myofascial release), which helps to reduce these restrictions by remobilizing the tissue through friction and mechanical stress, helping to return the fascia into its original gel - like state (3).

Other conditions that cause pimples on the head include stress, hot conditions, exposing the scalp to certain oils and chemicals, friction caused by helmets and hereditary acne.

Active Release Technique is used extensively by our chiropractors to treat injuries and conditions such as patellofemoral pain syndrome, iliotibial band friction syndrome, medial tibial stress syndrome (shin splints), achilles tendinitis, and plantar fasciitis.

The core - mantle boundary becomes increasingly viscous with increasing pressure at increasing depth, whence one can expect increasing «friction» leading to build - up of stress that is suddenly released on a quasiperiodic basis, possibly sychronized both with and by resonances in the cavity occupied by the mantle.

The power dissipation of a storm is proportional to the wind speed cubed (Emanuel, 2005a), as the main dissipation is from surface friction and wind stress effects, and is measured by a Power Dissipation Index (PDI).

Glacier - A mass of land ice that flows downhill under gravity (through internal deformation and / or sliding at the base) and is constrained by internal stress and friction at the base and sides.
