[Physical analysis on living tissues' thermal injury process]

Area of Science:

• Solid mechanics
• Thermal physics
• Biophysics

Context:

• Understanding thermal injury mechanisms in living tissues is crucial for clinical applications.
• Existing models may not fully capture the complex interplay of mechanical and thermal stresses.
• Subcutaneous bubble formation is a significant aspect of severe thermal trauma.

Purpose:

• To correlate physical factors causing thermal injury.
• To establish a novel thermomechanical model for quantitative analysis of heat-induced tissue damage.
• To interpret the three-stage mode of thermal injury in living tissues.

Summary:

• A new thermomechanical model is presented, integrating solid mechanics and thermal physics principles.
• The model quantitatively describes thermal injury progression in tissues subjected to heat.
• The study interprets a three-stage thermal injury process and investigates subcutaneous bubble formation and tissue disruption.

Impact:

• Provides a micro-mechanical and thermal science perspective on thermal injury.
• Aids in understanding the mechanisms behind subcutaneous bubble formation.
• Contributes to revealing the processes of thermal mechanical disruption in tissues.
