Title: | Coupled nonlinear problems in finite element analysis – a case study | Other Titles: | Spregnuti nelinearni problemi u analizi konačnim elementima – studija slučaja | Journal: | Structural Integrity and Life | Volume: | 12 | Issue: | 3 | First page: | 201 | Last page: | 208 | Conference: | Twelfth Meeting “New Trends in Fatigue and Fracture” (NT2F12) Brasov, Romania, 27–30 May, 2012 | Issue Date: | 1-Jan-2012 | Rank: | M24 | ISSN: | 1451-3749 | URL: | http://divk.inovacionicentar.rs/ivk/ivk12/ivk1203-9.html | Abstract: | The paper describes the Finite Element Method (FEM) analysis of elastic plastic deformation of steel tube impact absorbers for railway vehicles. Experiment investigation is used as a basis for FEM modelling and simulation. The developed FEM model includes material nonlinearity (plasticity), nonlinear contact and large deformation of finite elements. All aspects used in the absorber FEM model are explained in detail. The finite element analysis results for a chosen absorber are presented and discussed. The developed model opens the possibilities for future investigations of similar problems. |
