Dataset of 2D effective elasticity tensor from discrete simulations of quasi-brittle area elements

This dataset contains 76,356 effective elasticity tensors describing the degradation of quasi-brittle materials. The elasticity tensors are gathered from discrete (beam-particle) simulations of 2D area elements. Those simulations aim at reproducing the mechanical degradation of quasi-brittle materials submitted to complex (multi-axial and non-proportional) mechanical loads. Two types of data are given in this dataset: the damaging loadings and the effective elasticity tensors. Each damaging loading is stored in a CSV file. It contains a temporal index, the strain applied to the area elements, and the stress in response. The evolutions of each effective elasticity tensor are also stored in CSV files. It mainly contains the evolution of the effective elasticity tensor components during the associated damaging loading. It is also indexed with the same temporal index as in the damaging loadings files. The README.md file contains more details on the data and can be found below.
