Conical shells \ are of \ interests \ to \ many \ engineering \ branches. These shells are usually used as components for bearing pressure. For instance, in civil engineering applications, structures like; silos, pressure vessels, tanks, cooling towers and chimneys, involve conical shells in their constructions. Large conical tubes have a transition cone between two cylinders of different diameter. Conical reducers are used in oil transfer tubes for connecting two cylinder pipes of different diameter, and in places that do not fit the flange. Thus, these structures could be modeled as conical shells under internal pressure loading. Also, in the field of marine engineering, a body of submarines could be modeled as cylindrical shells with rigid reinforcement rings that are blocked by a truncated cone. In the field of aerospace engineering, a spacecraft cabin can also be considered a conical shell. In two recent applications, the model of conical shells is under external pressure. Therefore, due to the use of these structures, their analysis under pressure loads is essential and must be considered.In \ this \ paper, the \ plastic \ behavior of \ thin-walled \ ylindrical-truncated conical shells under static internal pressure will be investigated analytically. Towards this aim, the material behavior is assumed rigid-perfectly plastic, and a common rectangular surface has been used as the yielding criterion composed of stress resultants,
