In this work, we propose a framework for an adaptive contact analysis in deformable solids using the effective error indicator from the scaled boundary finite element method (SBFEM) with a quadtree decomposition. Further, the SBFEM is implemented with the commercial finite element software, Abaqus, to perform the contact analysis by employing the user element subroutine (UEL) feature. The SBFEM error indicator coupled with the quadtree decomposition is implemented in Matlab and allowed to interact with the Abaqus using .inp file for an adaptive refinement. The detailed implementation of the framework, input data format, and the UEL subroutine which is one of the key features of the proposed work are clearly explained. The effectiveness of the proposed framework is demonstrated by solving several contact problems of engineering significance.

在这项工作中，我们提出了一个使用可变形固体的自适应接触分析的框架，该框架使用了四叉树分解的比例边界有限元方法（SBFEM）中的有效误差指标。此外，SBFEM是使用商业有限元软件Abaqus实施的，以通过使用用户元素子例程（UEL）功能来执行联系人分析。SBFEM错误指示符与四叉树分解结合在Matlab中实现，并允许使用.inp与Abaqus进行交互文件进行自适应细化。框架的详细实现，输入数据格式和UEL子例程是拟议工作的关键特征之一，得到了清晰的解释。通过解决几个具有工程意义的联系问题，证明了所提出框架的有效性。可以从https://github.com/nsundar/sbfem下载开发的SBFEM代码。
