Metallic hyperstatic structures, like beams, submitted to excessive loads, do not fail completely before fully yielding in more than one cross section. Indeed, for built-in beams, three cross sections must be fully yielded before the final failure can occur. So, modeling the evolution of the cross-section residual stress distribution is an important subject that should be addressed to guarantee the stress analysis modeling correctness. This paper analyses the residual stress distribution evolution, in critical cross sections, of built-in beams during a transversal concentrated load growth, until the final failure through hinges formation. A finite element model is also presented. The results show good matches with the numerical model, used as a reference.

内置梁中的残余应力分布
金属超静力结构,如梁,承受过大的载荷,在一个以上的横截面完全屈服之前不会完全失效。事实上,对于内置梁,在最终失效发生之前,必须完全屈服三个横截面。因此,对截面残余应力分布的演化进行建模是保证应力分析建模正确性的一个重要课题。本文分析了在横向集中载荷增长过程中,内置梁在临界截面中的残余应力分布演变,直到通过铰链形成最终失效。还介绍了一个有限元模型。结果显示与数值模型匹配良好,用作参考。
