Lecture
This lecture covers the stresses in the wall of thin-walled pressure vessels, distinguishing between hoop and longitudinal stresses. The instructor explains the theory behind thin-walled pressure vessels and provides examples of their applications, such as scuba tanks and balloons. Through the analysis of different scenarios, students learn to calculate hoop stresses in various types of vessels, including healthy arteries and aneurysms. The lecture emphasizes the importance of understanding the geometry and loading conditions to determine the stress distribution in pressure vessels.
