On the yield strength of oceanic lithosphere
Web15 de mar. de 2024 · We computed the long-term yield strength of the lithosphere, that is, a proxy for the maximum differential stress that rocks are able to withstand without experiencing permanent deformation (Goetze & Evans, 1979) based on the approach described in Cacace and Scheck-Wenderoth ( 2016 ). WebThe origin of plate tectonic convection on Earth is intrinsically linked to the reduction in the strength of oceanic lithosphere at plate boundaries. A few mechanisms, such as deep …

WebWith increasing depth, the yield strength is large enough that the lithosphere will respond as an elastic plate to loading. The flexural response of the lithosphere to an applied vertical load depends, however, on whether there are any applied horizontal loads. Web1 de jun. de 2012 · The total lithospheric strength (σ L) is estimated through integration of the YSE. (1) σ L = ∫ 0 h σ 1 − σ 3 ⋅ d z where h is the thickness of the lithosphere. Strength for the brittle regime is described by Byerlee's law (Byerlee, 1978), which defines strength as a function of pressure and depth independent of rock type.As a result, the …
