Table 2 Material properties of the railway track model components used for FEA using ABAQUS
From: An impact echo method to detect cavities between railway track slabs and soil foundation
Track Components | Unit weight, γ (kg/m3) | Modulus of elasticity, E (Kpa) | Poisson’s ratio, v | Wave velocity (m/s) |
|---|---|---|---|---|
Concrete slab (TCL) | 2450 | 3.19e+07 | 0.15 | Â |
Concrete box (HSB) | 2445 | 2.58e+07 | 0.15 | 1100 |
Soil | 2000 | 80000 | 0.3 | Â |
