Dataset of solution files for generic contact mechanics model via modified penalty method based on power-law formulation

This dataset contains solution files for contact mechanics problems solved using a generic contact formulation implemented in the legacy version of the FEniCS open-source finite element library. The model is based on a modified penalty method with a power-law interaction formulation. Simulations capture the elastic deformation of components under four distinct contact conditions. The dataset is organized into four directories, each corresponding to a different problem scenario. For each case, separate VTU files are provided for each part in the simulation. These files include the x-, y-, and z-components of displacement (in mm), all components of the strain tensor, and all components of the stress tensor (in MPa). This dataset serves as a useful benchmark for researchers in contact mechanics, materials science, and mechanical engineering. Selected animations illustrating the solution evolution are also included in a separate file.

本数据集包含使用旧版FEniCS开源有限元库（FEniCS）中实现的通用接触公式求解的接触力学问题的求解文件。该模型基于带有幂律交互公式的改进罚函数法，仿真可捕捉四种不同接触条件下构件的弹性变形。数据集按四个目录组织，每个目录对应一种不同的问题场景。针对每个算例，均为仿真中的各个部件提供独立的VTU文件。这些文件包含位移的x、y、z分量（单位：毫米）、应变张量的全部分量，以及应力张量的全部分量（单位：兆帕）。本数据集可作为接触力学、材料科学与机械工程领域研究者的实用基准数据集。此外，单独文件中还包含部分展示求解过程演化的动画。
