摘　　要：针对Smith方法计算船体承载下的整个破坏过程,提出了一种以MFC为平台、OpenGL为图形接口的可动态显示的可视化方法,可以非常直观的分析整个过程中的中横剖面弯矩、曲率、中和轴以及截面各单元的应力变化情况,给研究船体极限破坏提供了的便利。By using the Smith＇s simplified method to calculate the hull longitudinal ultimate strength, the progressive collapse process can be traced from elastic situation to plastic situation. This paper selected a dynamic visualization method based on MFC and OpenGL graphic interface to reveal the collapse process lively. In this way, the changing situation of the bending moment, curvature and neutral axis, as well as the stresses distribution of the midship section can be observed and analyze intuitively during the whole collapse process.
