Web14 de fev. de 2014 · The depth integration of this yield stress envelope, and any deeper ductile support of stresses, determines the total strength of the plate. Where the stress does not exceed that supportable on faults, the plate behaves elastically; when it does, it will behave plastically. WebElasticity, plastic yielding, and viscous creep are therefore ingredients of the mechanical behavior of Earth materials. Each of these three modes will be considered in assessing flow processes in the lithosphere; these mechanical attributes are expressed in terms of lithospheric strength. city administrator lawson mo
