An analysis of the dynamical frictional unilateral contact problems of beam and plates on Hetenty’s foundation

 

In this paper the dynamical frictional contact problem of an elastic plate resting on a Hetény‘s foundation is analyzed from a computational point of view. The friction law assumed there is based on a regularization of Coulomlb’s classical law. The analysis concerns some one-dimensional models of beams and axisymmetric circular plates. The numerical investigation is carried out by a finite element approach and the time integration of thc discretized dynamical is obtained using a semi-imp1icit method.

The numerical results obtained show how the main parameters involved in the analysis influence the dynamical solution.
