PD理论提供了变形，以及损伤的启动和增长，而不诉诸外部的标准，因为材料失效调用的材料响应。然而，与有限元方法相比，它在计算上要求更高。此外，有限元方法是非常有效的建模问题没有损坏。因此，它是可取的耦合PD理论和有限元法，以利用其显着的特点，如果潜在的故障部位的区域被确定之前的分析。然后，可以使用PD理论对预期失效的区域进行建模，其余区域可以使用FEM进行分析。
The PD theory provides deformation, as well as damage initiation and growth, without resorting to external criteria since material failure is invoked in the material response. However, it is computationally more demanding compared to the finite element method. Furthermore, the finite element method is very effective for modeling problems without damage. Hence, it is desirable to couple the PD theory and FEM to take advantage of their salient features if the regions of potential failure sites are identified prior to the analysis. Then, the regions in which failure is expected can be modeled by using the PD theory and the rest can be analyzed by using FEM.
