This paper presents a method to analyze the fatigue damage growth and to estimate the damage of the hammer-foundation system due to repeated impact based on the concept of damage mechanics.

And it is a start when the damage is considered. That using a correct material constitutive equation is the foundation to set up a mechanics model.

采用材料恰当的本构关系是建立各类工程问题力学模型的基础。
