On the Use of Discrete-continual Finite Elements with Triangular Cross-section for Semianalytical Structural Analysis

This paper is devoted to theoretical foundations and verification aspects of the use of discrete-continual finite elements with triangular cross-section for correct semianalytical structural analysis. Application of L-coordinates, integration schemes, algorithms of computing of local and global stiffness matrices and verification samples are under consideration. Comparison of results, obtained by discrete-continual finite element method and conventional finite element method (with the use of ANSYS Mechanical) is presented.
