Effect of bending and compressive modulus of elasticity on the behaviour of timber-alternative railway sleepers supported by ballast [PDF]
Case Studies in Construction Materials, 2021 Alternative railway sleeper technologies for replacement of timber are made of materials possessing a wide range of bending and compressive moduli. This poses a great challenge to railway authorities and engineers in designing a railway track supported ...

Study on Influence of Ballast Spring Modulus on Track Structure Based on Finite Element Method
Frontiers Research of Architecture and Engineering, 2021 The finite element method is used to simulate the orbital structure, and the finite element model of "rail - sleepers - ballast" can be established. The model of the elastic modulus of different ballast and sleeper is calculated, and the rail displacement, the sleeper stress and the fastening force are deduced. The results show that the elastic modulus
