WebFormula for estimate the hoop stress of a cylinder is, Hoop stress = Internal diameter x Internal pressure/2 x Thickness. Mathematically hoop stress can be written as, σ θ = P.D/2t. Where, σ θ = Hoop stress in the direction of the both and unit is MPa, psi. P = Internal pressure of the pipe and unit is MPa, psi. WebThe maximum stress criterion, also known as the normal stress, Coulomb, or Rankine criterion, is often used to predict the failure of brittle materials. The maximum stress criterion states that failure occurs when the maximum (normal) principal stress reaches either the uniaxial tension strength σ t, or the uniaxial compression strength σ c, -σ
