J-integral data for determining minimum volume requirements for studies of microstructurally small cracks in heterogeneous, linear-elastic domains

The following data were generated from the finite element simulations described in “Determination of representative volume elements for small cracks in heterogeneous, linear-elastic domains” By DeMille and Spear. The data were then used in “Convolutional neural networks for expediting the determination of minimum volume requirements for studies of microstructurally small cracks, Part I: Model implementation and predictions” and “Convolutional neural networks for expediting the determination of minimum volume requirements for studies of microstructurally small cracks, Part II: model interpretation” by DeMille and Spear. The data include microstructure descriptions, J-integral values, and minimum volume requirements for the convergence of J-integral values with respect to volume size.
