4Pressure solution — or pressure dissolution in structural geology and diagenesis is a deformation mechanism that involves the dissolution of minerals at grain to grain contacts into an aqueous pore fluid in areas of relatively high stress and either deposition in… …
5Deformation mechanism — In structural geology, metallurgy and materials science, deformation mechanisms refer to the various mechanisms at the grain scale that are responsible for accommodating large plastic strains in rocks, metals and other materials. Contents 1… …
6deformation and flow — Alteration in size or shape of a body under the influence of mechanical forces. Flow is a change in deformation that continues as long as the force is applied. Gases and liquids normally flow relatively freely, while solids deform when subjected… …
7Pressure measurement — The construction of a bourdon tube gauge, construction elements are made of brass Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges. A… …
8deformation phosphene — Also known as pressure phosphene. The two terms are used interchangeably to denote a type of phosphene (i.e. seeing stars ) that can be provoked under physiological conditions by the exertion of gentle pressure on the eyeball. Deformation… …
