The study presents a framework for analyzing Additive Manufacturing processes within the Peridynamics (PD) software PeriLab. This framewor k employs a mesh‐free, point‐based numerical approach to approximate the continuum PD equations. Implemented within this framework are thermal, thermo‐mechanical, and simple additive models. These models have been validated against analytical solutions, Finite Element (FE) models, and Peridigm simulations. To leverage the PD mesh‐free implementation, the study introduces a novel boundary detection algorithm. This algorithm is essential because the outer surface area may change during the manufacturing process. It operates without requiring surface or topology information, relying instead on the comparison of neighborhood volume to sphere volume. Additionally, the study introduces a wrapper that generates the mesh necessary for simulating the printing process, based on the G‐code machine input path. Finally, the study presents a comprehensive analysis of an L‐shaped profile utilizing the developed features, comparing the results with those obtained from an Abaqus solution.

用于对增材制造流程进行建模的 Peridynamic 框架


该研究提出了一个框架，用于在 Peridynamics （PD） 软件 PeriLab 中分析增材制造过程。该框架 k 采用无网格、基于点的数值方法来近似连续体 PD 方程。在此框架内实现的是热、热机械和简单的增材模型。这些模型已针对解析解、有限元 （FE） 模型和 Peridigm 模拟进行了验证。为了利用 PD 无网格实现，该研究引入了一种新的边界检测算法。此算法是必不可少的，因为在制造过程中外表面积可能会发生变化。它的运行不需要表面或拓扑信息，而是依赖于邻域体积与球体体积的比较。此外，该研究还引入了一个包装器，该包装器根据 G 代码机器输入路径生成模拟打印过程所需的网格。最后，该研究利用开发的特征对 L 形轮廓进行了全面分析，并将结果与 Abaqus 解决方案获得的结果进行了比较。
