Lecture
This lecture covers the concept of hyperelasticity, focusing on the inflation of a balloon. The instructor explains the force balance on a hemisphere, thin-wall pressure vessels, and the behavior of incompressible hyperelastic materials. The lecture also delves into radius stretch, fixed volume conditions, and the deformation of hyperelastic materials. Boundary conditions and the process of inflating a spherical balloon are discussed, emphasizing the relationship between pressure, volume, and radius. The lecture concludes with insights on the difficulty of inflating larger balloons due to peak pressure variations.
