LCE: Meshless Methods for Life-Cycle Engineering Simulation

从算法的角度进一步发展了无网格粒子方法，使其具有鲁棒性、准确性和多尺度、多物理场的能力。通过开发的多尺度技术，获得了基于原子模型和晶格模型相结合的裂纹形成和动态扩展的新模型。由于许多原子和微观尺度上的性能都与材料加工有关，因此断裂性能是根据材料加工来确定的。这些模型通过先前发表的和正在进行的实验进行研究和验证。

The meshfree particle methods are further developed from an algorithmic viewpoint so that they are robust, accurate, and possess multiscale, multiphysics capabilities. Through the multiscale techniques developed, new models for crack formation and dynamic crack propagation are obtained that are based on combinations of atomistic and lattice models. Since many of the properties on the atomistic and microscale can be related to materials processing, fracture properties are identified in terms of materials processing. The models are studied and validated through previously published and ongoing experiments.
