In this Micro-Measurements® iLearn videos (two parts) , Tom uses a Micro-Measurements Advanced Sensors Technology rosette (CEA-13-125URA-350) and a System 8000 with StrainSmart Software to obtain principal strains and stresses, and their direction, on the aluminum wall of the soda can as the pressure within the can is relieved. The pressure developed in a soda can is determined by measuring the elastic strains on the surface of the can. Today, a pressure vessel (cylindrical or spherical) is designed to hold liquids or gases at a pressure substantially higher than the ambient pressure. The soda can is considered a thin wall pressure vessel model. In a thin wall pressure vessel, we measure two stresses: the longitudinal stress and the hoop stress. The longitudinal stress, hoop stress, and the internal pressure were calculated by StrainSmart and system 8000 from equations of generalized Hooke’s law for stress and strain.
Notes:
•Thin-walled pressure vessel is a condition where the thickness of the wall is negligible in comparison to other significant dimensions.
•An aircraft fuselage, gas tanks, human arteries, distillation towers, diving cylinder autoclave ,a balloon are all pressure vessels
