056912 - BIOMECHANICS AND THERMODYNAMICS
The Biomechanics Module aims to provide the students with fundamental knowledge about description and interpretation of biomechanical phenomena, with the aim to acquire ability to set and solve simple problems related to biological systems and tissues. Furthermore, the course introduces to fundamentals of materials and fluid properties, statics of structures, tissue mechanics and fluid motion. The Thermodynamics module aims to provide the physical and engineering bases of energy transformation processes, a prerequisite for the design of biomedical devices.
