shearbased

Shearbased is a term used to describe concepts, models, or materials in which shear forces or shear deformation play the central role in governing behavior. The word is formed from "shear" and the suffix "-based" and is used across disciplines to distinguish shear-dominated processes from those driven primarily by normal stresses such as tension or compression.

In practice, a shearbased approach prioritizes shear rate, shear stress distribution, and the orientation of shear planes when predicting deformation, flow, or failure. It is often contrasted with tension-based or compressive-based frameworks.

In materials science and engineering, shearbased models are used to study phenomena such as shear localization and shear-induced diffusion, and to design processes like metal forming, lubrication of interfaces, and the processing of anisotropic composites where shear flow controls microstructure evolution.

In geophysics and earth science, shearbased analysis is applied to fault mechanics, where slip on faults is governed by shear stress along fault planes, and to the study of earthquake nucleation and propagation under shear-dominated conditions.

Advantages of a shearbased perspective include direct alignment with the primary force that drives many deformation processes and potential improvements in predictive accuracy for anisotropic materials. Limitations include potential neglect of coupled normal stresses, complex three-dimensional effects, or multi-physics couplings such as thermal and chemical interactions.
