摘要

在这项工作中，扩展了粒子有限元方法(PFEM)来模拟各种不同复杂几何形状的增材制造过程。采用三维α-形方法进行材料添加。它克服了仅采用传统元素生死技术的局限性，与此技术相比，降低了自由度。最后，通过数值算例验证了PFEM方法在弱耦合热弹性公式框架下对增材制造的适用性。在增材制造操作中，挠度、应力和温度是使用fenic中用户定义的实现来计算的。

A Particle Finite Element Method for Additive Manufacturing Simulations

In this work, the particle finite element method (PFEM) is extended to simulate additive manufacturing processes in a variety of different complicated geometries. A three-dimensional α-shape approach is used to carry out the material addition procedure. It overcomes the limitation of merely employing the traditional element birth and death technique and reduces the degrees of freedom compared to this technique. Furthermore, numerical examples are used to evaluate and demonstrate the applicability of the PFEM method for additive manufacturing within the framework of a weakly coupled thermoelasticity formulation. During additive manufacturing operations, deflections, stresses, and temperature are computed using a user defined implementation in FEniCS.

期刊介绍： The ASME Journal of Computing and Information Science in Engineering (JCISE) publishes articles related to Algorithms, Computational Methods, Computing Infrastructure, Computer-Interpretable Representations, Human-Computer Interfaces, Information Science, and/or System Architectures that aim to improve some aspect of product and system lifecycle (e.g., design, manufacturing, operation, maintenance, disposal, recycling etc.). Applications considered in JCISE manuscripts should be relevant to the mechanical engineering discipline. Papers can be focused on fundamental research leading to new methods, or adaptation of existing methods for new applications.
