Tank containers are intermodal containers for the transport of liquids, gases, and powders as bulk cargo However, hazardous vibration during transportation would generate fatigue damage at discharge area. This thesis aims at calculating fatigue damage at discharge area of a specified tank container.

The calculation is performed in time domain. With FEM models and measured input, hot spot stress is calculated for each hot spot. Probability distributions projects the stress distribution to a longer period thus fatigue damage for 20 years is calculated.

The available data consists of acceleration and velocity of the container during a typical train transportation. A global model and a local model are established with FEM software package. Experimental data from the Lloyd register are used to verify the global model.

In conclusion, during the typical transportation period, fatigue will occur at one of the hotspots.
