Thermal Effects: Hyperstatic Systems

This lecture covers the resolution of hyperstatic systems with temperature variation, the effect of temperature on stress and strain in materials, and the concept of hyperstatic problems. It explains how materials expand with temperature, the coefficient of thermal expansion, and the generation of thermal effects. The lecture also discusses relative thermal strain, internal forces due to geometric constraints, and the impact of temperature on structures with different supports. Additionally, it explores indeterminate systems, redundant forces, equilibrium equations, and the compatibility equation in hyperstatic structures.
