Think of strain as percent elongation – how much bigger (or smaller) is the object upon loading it. Just like stress, there are two types of strain that a structure can experience: 1. Normal Strain and 2. how do i eliminate a facebook account

"WebbWhen subjected to stress, brittle materials break with little elastic deformation and without significant plastic deformation. Brittle materials absorb relatively little energy before fracture, even those of high strength. In brittle fracture (transgranular cleavage), no apparent plastic " - Small deformation

WebbAbstract. Small faults with displacements of a few millimeters or centimeters are abundant in the Entrada and Navajo Sandstones, in the San Rafael Desert, Utah, where they are important primary structures, preceding the development of large faults with displacements of several meters or tens of meters. The small faults contain no surfaces … Webb24 dec. 2008 · We develop a thermodynamic model of electrostriction for elastic dielectrics capable of large deformation. The model reproduces the classical equations of state for dielectrics at small deformation, but shows that some electrostrictive effects negligible at small deformation may become pronounced at large deformation.
