Verification of the LIRA-FEM software / Тест 4.14 Console stability with no force (new) / Analytical solution: A. V. Perelmuter, V. I. Slivker Stability of structures and related issues, Moscow: SCADSOFT Publishing House, 2007, p. 585. 585.
Analytical solution: A. V. Perelmuter, V. I. Slivker Stability of structures and related issues, Moscow: SCADSOFT Publishing House, 2007, p. 585. 585.
Geometry:
![]() |
L = 10 м; |
Material characteristics: EF = 1000 т, ЕIy = EIz = 10 тм2, GI = 10 тм2.
Boundary conditions: Точка А защемлена.
Stresses: P = 1 т.
We used rod finite elements ( FE 10), breakdown is 100 FE. The load application nodes are absolutely rigid bodies.
Formulas (3.3.20) from the book by A.S. Gorodetsky and I.D. Evzerov Computer models of structures were used for constructing the stability matrix./i>, М. «АСВ», 2009.
