“…This mechanism is one of the most popular and has been widely used in ABAQUS to simulate realistic concrete behaviour. It was found that this mechanism can represent closely to the actual crack pattern as seen in previous studies [32][33][34][35]. The Eq.…”

“…However, it is impossible to conduct 102 a crack propagation analysis with the CDP models as the CDP concept does not employ a failure 103 criterion. The CDP is one of the most popular concrete models and has been used for concrete 104 behaviour simulation in ABAQUS as seen in the literature [32][33][34][35]. This model was theoretically 105 described by Lubliner et al [32] and developed by Lee and Fenves [33] To enable the study of crack propagation of the sleeper models under impact loading, an alternative, the brittle cracking model, has been suggested [36][37].…”

“…Numerical modelling is an ideal tool to enable complex structural scenarios to be replicated and analysed, providing insights that would be beneficial for solving issues without using a huge amount of resources as traditional experimental methods would. Two different methods, the concrete damaged plasticity (CDP) model [32][33][34][35] and the brittle cracking model [36][37] are used to compare the results. The CDP model is designed based on two failure mechanisms, tensile cracking and compressive crushing.…”

However, the accuracy of FEM is greatly considered by the parameters input, in particular by selecting a suitable material property and its constitutive model [3,50].…”

Analytical Study of Rectangular Concrete-Filled Tubes (RCFT) Connections using Finite Element Analysis under Cyclic Loading

2022

Recent condition of the earthquakes model has shown that rectangular concrete-filled tubes (RCFT) with weld connection are so brittle. According to the studies conducted, large damages are due to the cracking of the weld between the beam flange and the column face and inducing concentrated stresses in this area. One of the novel alternatives to reduce the stress concentration at the panel zone could be the use of the reduce beam section (RBS). Given the enormous impact of seismic behaviour and ductility of the panel zone, RBS moves plastic hinges formation at an appropriate distance from column face. In this study, 2 major model of RCFT with and without RBS have been modeled using ABAQUS computer program and compared under cyclic behaviour. The obtained result of this study showed that using RBS is more ductile and implied a good stability. It also will consider having better ductility than other connections. GRAPHICAL ABSTRACT

Dynamical response of railway switches and crossings

et al. 2017

Abstract.A procedure for the numerical analysis of the dynamic response during the passage of railway vehicles is described. The solution is based on the finite element method (FEM), which is used for the calculation of track stresses. An FEM model was used with a fine structure that included all components of switches and crossings, including movable parts. The excitation forces are defined on the basis of the assumed interaction between track and vehicle. The track stiffness defined by FEM analyses is used for the calculation of dynamic vertical and lateral wheel load. A special model of a railway vehicle was built with the aim of calculating the forces at points where abrupt stiffness changes occur, as well as geometrical imperfections in the frog structure.
