Geometry-controlled rheological transitions in block-in-matrix systems: A mechanical framework for deformation in subduction mélanges

This dataset contains numerical results from finite-element modeling of deformation in a block-in-matrix system. It includes data for the phase diagram and shear stress evolution, as well as time-dependent model outputs stored in MATLAB format (.mat files). The MATLAB files preserve the original structure of the unstructured finite-element mesh and include spatial distributions of shear stress and shear strain rate, together with mesh geometry and simulation parameters.
