Elasto-plastic Stress Analysis for Hydraulic Cylinders Tube of Thick wall

후벽 유압실린더 튜브의 탄소성 응력해석

This paper was utilized the STKM13C tubes for machine structural purposes model, inner radius was 100 mm and outer radios was 140 mm, axial length was semi-infinite and the isoparametric element was used. Radial, tangential and shearing stress occured the maximum stresses(-20, 52 and 26 MPa) at the inner radius and the minimum stresses at the outer radius. of the hydraulic actuator cylinders for an industrial systems. But negative signs have meaning compressive stress and stress diminution ratio was about 0.15 MPa/mm And then coincidence between the simulation and exact results(Lame' equation) is found to be fairly good, showing that the proposed analytical by BEM are reliable.
