摘要
本文引用了由幂次硬化材料(σ=Kε~n)的板冷弯成管状构件所形成残余应力的近以计算公式,而对于焊接,则采用一种典型的残余应力分布形式,用有限元法研究了冷弯和焊接残余应力对受轴压的海洋工程管状构件屈曲荷载的影响。
In this paper approximate formlas for residual stresses due to cpld bending for materials with stress-strain curves of the form σ=K_ε are adopted.A typical distribution of the lougitudinal residual stress due to welding is also adopted.The effects of residual stress due to cold bending and welding on plastic buckling of axially compressed cylindrical shell are calculated.
