Part of bachelor's thesis is numeric simulation of several testing variants of wholewood carpentry joints during mechanical strain. As a type of test was used 3 and 4 spots bend for symmetric and asymmetric loaded joint.There were tested a joints with two different dimensions. Purpose of this test is elaboration, evaluation and comparison of joint behavior. For simulations is monitored the process of Ansys Workbench tool, that means, Individual steps from creation of geometric model trough networking, defining of material attributes, determination of boundary conditions solution to exportation of results. Basic joint designs were taken from destruction tests ongoing within "Design and evaluation of historical construction carpentry joints" project, which followed up the design of wholewood joints and destruction tests. This project is showing complex joint response by using a method based on finite element method. The results of the project will be used for comparison with experimental data and then used to examine alternatives joints. |
