Srovnání numerických výpočtů statického zatížení nosníku

This bachelor thesis is focused on wooden beams with rectangular cross-section. During static assesment of beams is suitable to calculate the deformations of beam as accurately as possible but linear elastic material models underestimate it as long as load exceeds linear elastic limit from which the material behavior is nonlinear. It is better to use elasto-plastic material model to describe a real behavior of wood. The aim of the work is to analyze and compare linear and nonlinear behavior of wooden beam for different boundary conditions. This work deals with spruce beam, two kinds of loads and two kinds of supports. The numerical solution is based on finite element method in Ansys software using 1D as well as 3D elements. Numerical results were compared with analytical solution to validate the numerical model for all variants of beam with linear elastic material.
