WebJul 12, 2024 · Circumferential or hoop stress Let us Consider a thin cylindrical shell subjected to internal pressure and A tensile stress acting in a direction tangential to the circumference is called circumferential or hoop stress. In other words, it is tensile stress on the longitudinal section (or on the cylindrical walls). Where, WebThe maximum stress is the circumferential stress, ¼ PR=t . The minimum stress is the radial stress,r r¼ P Therefore, the maximum shear stress is: r 2 ASME Code, Section VIII, Division 2, and Section III use the term ‘‘stress intensity,’’ which is defined as twice the maximum shear stress. how many g summits are there https://puntoholding.com
