Thank you very much for your course. I would like to know how to calculate the outer diameter of a thick-walled cylinder under internal pressure under the condition of axisymmetric plane strain
Hello / I want to make a T6 7075 aluminum cylinder with an outer diameter of 50 mm and I want to fill it with air with a pressure of 30 Mpa / What is the wall thickness needed to withstand such pressures
i have a question, longitudinal stress try to increase the length of the vessel and radial stress try to increase the diameter of the vessel .what about hoop stress ? what hoop stress will do?
Hoop stress tries to increase the diameter, not radial stress. Radial stress is the compressive stress in the direction from the inner layers of the material to the outer layers (orthogonal to both longitudinal and hoop). It is the highest at the inner diameter (equal to the fluid pressure) and zero at the outer surface. It can be like layers of duct tape tightly wrapped around some objects. as the objects expand/move/are added to, one layer of tape pushes outwardly on the next - that is the radial stress. I hope this helps. Thanks for watching and commenting!
please solve this qis if you can plz . A cylinder with closed ends has outer diameter D and a wall thickness t = 0.1D. Determine the %age error involved in using thin wall cylinder theory to calculate the maximum value of tangential stress and the maximum shear stress in the cylinder. (tangential stress ± 9.75% : max. shear stress ± 11.1%)
Thank you for the video! Great class!
Very clear explanation! Thanks!
