Abstract
This paper proposes an in-situ fatigue-crack assessment of the cement rotary kiln shell that is fabricated with weldments of steel base plates of ASTM A516 grade 70. The objective of this research is to obtain the fatigue life and crack initiation within the kiln shell using the method of strain-based fatigue analysis under the low cyclic loading condition. This can be achieved by using the nonlinear finite element analysis to obtain simulation for predicting service life and damage regions on the certain location where cracks are initiated. It is started by using the data from the preliminary stress analysis based on the nonlinear static study of the shell. The 3D solid model of the shell is converted into solid. The fatigue study will run after applying the S-N data of steel fatigue properties from previous experiments and defining the loading scenario based on static analysis result demonstrating the stress distribution and factor of safety within the kiln shell structure. From the simulation results, it is obtained that the static stress 19.131 MPa on the kiln shell due to the clinker load does not influence significantly to the failure of the kiln shell rather than the thermal load. The kiln shell has the total life cycles of 960.800 times before the crack may occur. The structural failure begins to damage by crack initiation at the potential location nearby the burning zone which located at the 22-28 meters from the outlet of the kiln shell.
