Benchmark simulations of elastic problems using a Cosserat-enhanced Non-Ordinary State-Based Peridynamics model

This dataset contains numerical results from simulations of elastic problems performed using a Cosserat-enhanced Non-Ordinary State-Based Peridynamics (SCPD) model. Four benchmark cases are included: uniaxial tension, simple bending, uniaxial tension of a plate with a circular hole and uniaxial tension of a plate with central crack. In all cases, a rectangular plate of dimensions 20 × 20 mm is analysed under plane stress conditions.
The data were generated using the Julia Peridynamics package combined with a dynamic relaxation time-integration algorithm. The computational domain was discretized using uniform grid spacings of 0.25, 0.5, and 1.0 mm. Simulations were carried out for various values of the internal material length-scale parameter (see related publication) to examine its influence on displacement fields, stress fields, and couple-stress distributions.
Material parameters were set to Young’s modulus E = 210 GPa and Poisson’s ratio ν = 0.3 and 0.45. The dataset provides benchmark solutions useful for validating advanced peridynamic models and studying size-dependent behaviour in elastic solids.
