Generalized Hooke's Law

Generalized Hooke's Law

The generalized Hooke's Law is a broadened version of Hooke's Law, which extends to all types of stress and in every direction. Consider an isotropic material shaped into a cube subjected to multiaxial loading. In this scenario, normal stresses are exerted along the three coordinate axes. As a result of these stresses, the cubic shape deforms into a rectangular parallelepiped. Despite this deformation, the new shape maintains equal sides, and there is a normal strain in the direction of the...

Thermal Strain

Thermal Strain

Thermal strain is a concept that arises when we consider how temperature changes affect structures. Unlike the conventional assumption that structures remain constant under load, real-world scenarios often involve temperature fluctuations that can significantly impact these structures. Consider a homogeneous rod with a uniform cross-section resting freely on a flat horizontal surface. If the rod's temperature increases, the rod elongates. This elongation is proportional to the temperature...

Background:

Understanding thermo-mechanical responses in skin is crucial for thermal therapies.
Accurate modeling is needed to avoid unrealistic predictions in heat transfer and mechanical effects.
Existing models like Pennes' may yield unrealistic outcomes in certain conditions.

Purpose of the Study:

To analytically investigate the thermo-mechanical behavior of 2D skin tissues under instantaneous heating.

Application of Laplace and Fourier integral transformations.
Numerical inversion using the Stehfest method for transform inversion.

Main Results:

Blood perfusion rate and thermal relaxation time significantly impact thermo-mechanical distributions.
Thermo-mechanical waves propagate finite distances within the skin tissue.
The model provides a more realistic prediction compared to the Pennes' model.

Conclusions:

The study provides a refined analytical model for skin's thermo-mechanical response to heating.
Findings highlight the importance of blood perfusion and thermal relaxation time in thermal therapy.
The developed model mitigates unrealistic predictions associated with simpler heat transfer models.
