On the time of existence of weak discontinuity waves in poroelastic materials


  • Wilmański, Krzysztof




In the paper, we consider the possibility of the growth of strong discontinuity waves in the two-component poroelastic materials. We use the model with the hyperbolic set of field equations described in the paper K. Wilmanski [19961]. It is shown that indeed the critical time (i.e. the maximum time of existence of classical solutions) is finite and it assumes realistic values for real physical systems, such as biological tissues.
