Stress Concentration Calculation of Silo Wall Opening Subjected To In-Plane Tension or Pressure

摘要

In this paper, by using complex variable function and conformal mapping technique, the author studies the stress concentration intensities of silo wall opening through predigesting the stress calculation of silo wall opening as a problem of plane calculation and obtains the stress concentration factor of opening. When simplified silo wall is subjected to in-plane tension or pressure, maximal stress concentration point around opening is at the corner of opening. this paper may provide some referenced value to the designers.
