Gradient damage for dynamic analysis

Hi all,

I would like to implement a gradient enhanced damage model for a 2D beam under dynamic loading (time-dependent). The model is nonlinear elastic isotropic damage model. Since the load applied on the beam is time-dependent, the equivalent strain and danage should also be time-dependent. My question is : when formulating the balance of momentum how can I obtain the strain as function of time ?

Thank you in advance.

Best regards.
