摘要：In this talk, we share our work on the numerical approximation for the two-dimensional three-component (2D-3C) shallow shell problems. The clamped plate and shallow shell structures are non-negligible in engineering, especially in architectural design, aerospace, and automated manufacturing. Therefore, it is crucial to develop efficient numerical algorithms to analyze their mechanical behavior accurately. In solving such problems, we face two significant challenges. On the one hand, the complex variable coefficient system on the 2D surface complicates the discretization process. On the other hand, the displacement components have a high degree of regularity, further increasing the difficulty of discretization. We introduce discretization schemes of conformingandnonconformingFEMsand virtual elements to meet these challenges. Moreover, the new contributions include well-posedness and stability for the approximate problem and analysis of the convergence of the numerical solution. Finally, numerical results show that the stability and convergence of the numerical schemes are verified.
