Structural stability study for porous Cosserat media

In this paper we approach the linear mixed problem with initial and boundary values for a Cosserat body which is elastic and has pores. We coupled the equations characterizing the pores evolution with basic equations that describing the elastic deformations of the Cosserat body. The coupling is done by means of predetermined coefficients. To prove the continuous dependence of the solutions, we introduce an adequate measure which is useful in obtaining of some estimations with respect to the gradient of elastic deformations and regarding the gradient of a specific the application, introduced to characterize the behavior of the pores.

Automated summary

In this paper, we study the linear mixed problem with initial and boundary values for a Cosserat body that is both elastic and porous. We couple the equations governing the evolution of the pores with the equations describing the elastic deformations of the Cosserat body. The coupling is achieved through predetermined coefficients. To prove the continuity of the solutions, we introduce a suitable measure that helps in estimating the gradients of the elastic deformations and the behavior of the pores.
