Swelling porous elastic soils with fluid saturation and delay term in the internal feedback
摘要
This work addresses a problem related to the one-dimensional system in the linear isothermal theory of swelling porous elastic soils under the influence of a fractional delay mechanism. Using classical semigroup theory, we prove the existence of a global solution under a smallness condition on the fractional delay. Furthermore, we apply the energy method without assuming equal wave speed propagation to demonstrate exponential stability.
