A MGT thermoelastic problem with two relaxation parameters
(Springer Nature, 2023-10)
Article
Accés obertn this paper, we consider, from both analytical and numerical viewpoints, a thermoelastic problem. The so-called MGT model, with two different relaxation parameters, is used for both the displacements and the thermal ... -

Article
Accés obertDegradation of solids bearing load due to the infusion of moisture when exposed to the environment can leads to a decrease in their load carrying capacity and can also lead to the failure of the body from performing its ... -
Analysis of two thermoelastic problems with the Green–Lindsay model
(Springer, 2023-06-01)
Article
Accés obertIn this paper, we analyze, from the numerical point of view, two thermo-elastic problems involving the Green–Lindsay theory. The coupling term is different for each case, involving second order or first order spatial ... -
Anisotropy can imply exponential decay in micropolar elasticity

Article
Accés obertIn this note, two problems arisen in micropolar elasticity are considered from the analytical point of view. Following the Kelvin–Voigt theory of micropolar viscoelasticity, two dissipative mechanisms are imposed: in the ... -
