| 中文摘要: |
| 损伤与断裂是导致结构失效的主要原因,对工程安全有着重大影响,其中裂纹扩展问题也是目前亟需解决的基础性科学难题。本文介绍了能够模拟损伤与断裂的相关理论基础如断裂力学模型、损伤演化模型,以及数值计算方法如有限元法、边界元法和近场动力学理论等。在此基础上,对常用的结构损伤与断裂分析CAE软件进行了综述,包括通用有限元程序如ABAQUS自带的损伤与断裂分析模块,以及专用的断裂分析软件、损伤容限工具和疲劳寿命分析工具等。讨论了部分自主的CAE软件的发展现状。最后,分析了用于损伤与断裂模拟的CAE软件面临的一些挑战,并展望了国产CAE软件未来的发展方向。 |
| 英文摘要: |
| Damage and fracture are the main causes of structural failure,which have a significant impact on engineering safety.Crack propagation problem is also a fundamental scientific challenge that needs to be solved urgently.In this paper,the relevant theoretical basis for simulating damage and fracture,such as a fracture mechanics model,damage evolution model and numerical calculation methods,such as the finite element method,boundary element method and peridynamics theory,are introduced in the form of literature review.This paper also reviews the commonly used CAE software for structural damage and fracture analysis,including general-purpose finite element programs such as the damage and fracture analysis module that comes with ABAQUS,as well as specialized fracture analysis software,damage tolerance tools,fatigue life analysis tools,etc.The development status of some autonomous CAE software is also discussed.Finally,this paper analyzes some challenges faced by CAE software for damage and fracture simulation,and looks forward to the future development direction of domestic CAE software. |
