“…Besides large deflections, in boundary element methods post-buckling behaviour can also be taken into consideration [21,22]. In order to combine the advantages of finite and discrete element methods there has been a development of a shell analysis by using a combined finitediscrete element method (FDEM) [23][24][25]. This approach uses an explicit time integration scheme (there is no need for stiffness of mass matrices), making it robust and suitable for parallel programing.…”

“…The main purpose of this paper is to demonstrate computational aspects of the two numerical models (2-TRIELS [24] and 4-TRIELS [25]) for a static and dynamic analysis of shells based on the combined finite-discrete element method. The dynamic and static response of shells under various boundary conditions and mesh refinements was analysed and compared with reference solutions in order to illustrate the accuracy and the field of application of the proposed numerical model.…”

This paper demonstrates some computational aspects of two previously developed numerical models for a static and dynamic analysis of shells based on the combined finite‐discrete element method. The dynamic and static response of shells under various boundary conditions, mesh pattern and mesh refinement was analysed and compared with other numerical and analytical results in order to illustrate the accuracy and applicability of the proposed numerical models.

“…All previously mentioned numerical algorithms are implemented in the open source Y2D (for 2D analysis) and Y3D (for 3D analysis) numerical code. The FDEM has found wide application in various fields of science such as structural analysis [14][15][16], rock mechanics [17,18], maritime engineering [19], biomedical engineering [20] and mechanical engineering [21]. Sequential CPU algorithms for FDEM problems have been developed, including Munjiza-NBS [22] and MR [23] algorithm for contact detection, combined single and a smeared crack model for fracture and fragmentation [24], penalty function method based potential contact force for contact interaction [25], and time saving algorithms for force evaluation [11].…”

GPU based parallel FDEM for analysis of cable structuresA combined finite-discrete element method, adapted for the analysis of a parallel cable element model using graphic cards, is presented in the paper. The basic objective is to speed up sequential computation time by one or two orders of magnitude. Paralelni model kabela za grafičke kartice baziran na metodi konačno diskretnih elemenata U radu je prikazana adaptacija kombinirane metode konačno diskretnih elemenata za paralelni model kabelskog elementa pomoću grafičkih kartica. Osnovni cilj je ubrzanje proračunskog vremena serijskog koda za jedan ili dva reda veličine. Razvijeno rješenje je implementirano unutar slobodno dostupnog FDEM Y koda. Mjerenje performansi razvijenog rješenja kao i diskusija o tome prikazani su na jednostavnim primjerima. In der Arbeit wird die Anpassung der kombinierten Methode der finiten diskreten Elemente für ein paralleles Kabelmodell anhand von Grafikkarten dargestellt. Der Schwerpunkt lag dabei auf der Beschleunigung der Berechnungszeit des Seriencodes um eine oder zwei Größenordnungen. Die entwickelte Lösung wurde innerhalb der frei zugänglichen FDEM Y Codes integriert. An einfachen Beispielen wurden die Messung der Leistungen der entwickelten Lösung sowie entsprechende Diskussionen dargestellt.

“…While various methods and the associated algorithms, for example the combined finite-discrete element method (FDEM) presented in [5], are being developed continuously to overcome the limitations of the FEM, increasingly including greater details in modelling complex systems in a quest for higher fidelity and realistic model is also an important trend in the FEM advancement. Full vehicle crash simulations, including passenger car and motorcycle, are one of the representative examples with such progression.…”

This paper describes the development of a fully deformable finite element model of an upright telescopic motorcycle front fork in LS-DYNA environment. The modelling for each of the key components, overall assemblage, and contact interactions involved were presented. Comprehensive validation was performed by comparing the reaction forces in a quasi-static test performed on a universal testing machine with customised fixture, which was specially designed to impose compressive and bending load simultaneously on the fork unit throughout the process. The behaviour of the fork under such loading conditions was studied and explained. Significant localised deformations observed on the components were also identified and compared. The results from the simulations were found to be well agreed to that of the physical testing, with closely matching profile of the reaction forces and a deviation of 1.4 % based on the work done to deform the fork. Major considerations for establishing the full model were concluded and recommendations were suggested for improvement.
