双向应力椭圆计算的理论精度

THE ACCURACY OF BILATERAL STRESS ELLIPTIC THEORY

    摘要
  • 摘要: 作为第四强度理论的近似计算,目前在套管柱强度设计中广泛应用双向应力椭圆理论。对双向应力椭圆理论的适用性和计算误差进行了分析。双向应力椭圆理论用于套管柱设计能满足工程需要。

     

    Abstract: The Bilateral Stress Elliptic(ellipse of plasticity) Theory is widely used in casing strength designing, as an approximate alternative to the fourth strength theory. This paper analyzes the feasibility and tolerance of Bilateral Stress Elliptic Theory, and it concludes that it can meet the engineering requirements of casing designing.
