Numerical Analysis of a Swelling Poro-Thermoelastic Problem with Second Sound

Global Existence and Exponential Decay for a Dynamic Contact Problem of Thermoelastic Timoshenko Beam with Second Sound

In this paper, we study the global existence and exponential decay for a dynamic contact problem between a Timoshenko beam with second sound and two rigid obstacles, of which the heat flux is given by Cattaneo’s law instead of the usual Fourier’s law. The main difficulties arise from the irregular boundary terms, from the low regularity of the weak solution and from the weaker dissipative effec...

Poro-thermoelastic Mechanisms in Wellbore Stability and Reservoir Stimulation

Some fundamental mechanisms associated with cooling/heating of the rock in the context of drilling and reservoir stimulation in enhanced geothermal systems are described. The role of temperature and pore pressure in wellbore failure and fracture width is considered using analytical and boundary element models. Results indicate that cooling induces a pore pressure drop inside the formation that ...

Asymptotic Behavior of Discontinuous Solutions to Thermoelastic Systems with Second Sound

On a contact problem in thermoelasticity with second sound

We investigate the existence and stability of a thermoelastic contact problem with second sound. Previous results established the existence and stability of a solution of the corresponding classical system in the case of radial symmetry. However, recent works have shown that sometimes stability can be lost when the classical Fourier heat conduction is substituted by Cattaneo’s Law. We show that...

the effectiveness of strategy-based instruction in teaching english as a second or foreign language: a meta-analysis of experimental studies

a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
